9 Steps To Make Your Old Personal Computer Work As New (part 1)

Maintenance is the last thing on your mind when you buy a new computer, for a good reason: your new computer should be able to handle everything that you throw at it!

Unfortunately, it is this mentality that leads to a general situation with PC users: slow and can not be used by a computer, well before the computer expiration date.

Many people think that this is just normal, and that the normal life cycle for the computer is under 2 years. This is not the case! We want to help people get more life out of their computers, so we developed this list of steps that anyone can follow to bring their computer back to peak performance. Follow these tips in the order and your computer will work like new! We hope that you will find these steps valuable!

Here is a list of steps to create your old PC to run like new; read below for more details on how to perform each of them.

Nine-Step ReviverSoft Plan

Secure PC
Remove unnecessary applications
Stopping the program does not start at boot time
Start Windows Update
Updating the drivers of your computer
Running Disk Cleanup
Removing the Browser Add-ons
Run the Windows registry scan,
Defragment your hard drive
Below is each step in order of execution, with detailed information on how to perform each of them no matter what version of Windows you have.

Step 1: Protect your computer

How to do this you can watch in our facebook page – https://www.facebook.com/Electronics-Repair-Cincinnati-334626130374166/

Before you get started, trying to fix all the problems on your computer and run the necessary maintenance, first make sure that there are no security problems on your computer, such as viruses or malware. Some malware and viruses can cause serious performance problems. You will not be able to remove them using the typical methods of uninstalling the software, so it’s always better to use a reliable and authoritative security application.

ReviverSoft recommends two applications; one carries costs, and the other is free.

Norton Internet Security has a decade-long reputation for bloating your computer’s belly and making it slow and difficult to use, but over the past few years it was actually the exact opposite of this. Norton now uses few resources and provides the level of security that has made this the choice of editors among the security software reviewers.

Our free recommendation is Malwarebytes Anti-Malware. Malwarebytes has long been a favorite security application for technical personnel (we even heard stories where technical support from people from other security recommend Mawarebytes to their customers). The application is known for its ability to detect almost all malware.

Download and run one or both of these applications, and then run a scan system for each one to make sure that your computer has not been compromised.

Step 2: Remove unnecessary applications

Over time, when you use a computer for various purposes. You can use it to develop something, play games and music, chat with friends, burn CDs, record music or any number of other things. You need an application for each of these purposes. Quite often, you can install something and use it only once, or you can use it for a short period of time, and then stop using it. Each application installed on your computer takes up space, can run in the background while you use your computer, and many even make your computer start slower. That’s why we recommend that you uninstall any application you do not use.

Windows makes it very easy to uninstall the application. We have a great article on how to remove the software from your computer.

It always feels great to throw things that you do not need, and the same is to remove applications that you no longer use. Be ruthless! You can always go back and download the application later, and if it’s a long time between uses for a particular application, then most likely the update is needed before you can use it again anyway and the update can only take as long as Download All this.

Stress Test for Video Cards and Aida64 Program (part 2)

After an in-depth inspection for breakdowns, you should proceed to a software test. There are already many more things that affect performance.

The best (and time-tested) way to make a video card a hot day is the Aida64 program (formerly Everest). This is a comprehensive solution for system improvement, physical monitoring and software analysis at different levels, temperature sensors. But stress tests deserve special attention.

We are interested in the video card, so in the context menu of the program it is necessary to go into the Service and select the GPGPU Test:

The context menu of the program Aida64
Next, a window will open where you need to uncheck the processor name and leave it in front of the video card. Note the abbreviations:

The GPU is a Graphics Processing Unit (graphics processor, that is, a graphics card);
The CPU is the Central Processing Unit (the central processor that is installed in the center of the motherboard).

Uncheck
Next, the Start Benchmark button is pressed, and the results of the health check are evaluated according to your knowledge in this matter.

If no errors appear during the check, then at least with it everything is in order. But this test does not heavily burden the system, but rather gives more professional information about the operation of the video card. What, then, should an ordinary user do? Usually he types in Google: electronic repair service near me

Of course, a stress test. In the Service tab, select the System Stability Test:

Stress test
It is necessary to remove the tick from all points except the GPU, and click Start. A couple of minutes will be enough to check how strong your video card is, and how much it can withstand.

It is highly discouraged to perform such tests for more than 20 minutes – this can lead to equipment failure.
In this window, you can monitor a variety of data (temperature, cooler rotation, voltage, etc.) right during the test. If during the testing with the system nothing happened, there are no critical marks, and the video card continues to work properly, the device’s performance is excellent.

Stress test with FurMark

The stress test for video card performance by FurMark (and similar) is performed by each individual user exclusively at own risk and risk. If the equipment deteriorates, no one will be held responsible for this, except for you.

In the event of a final decision to check the video card on a stress test, FurMark will cope with this perfectly. Although, this is how to look, because this program loads the video card in the course of testing, as no existing game or application (or several) can do at the moment. Therefore, during the verification of the video card, you should always be ready to turn off the check at any time and keep the equipment in working order.

The program is distributed free of charge (it is best to download from the official site), and when it starts, the following window will appear:

Running FurMark
In the drop-down list, you need to select the resolution of your screen (for stationary computers this is often 1920×1080, but it can vary), and then press the Settings button.

In the settings, you need to check the box next to Dynamicbackground and Burn-in.

Checkboxes opposite Dynamicbackground and Burn-in
It is highly recommended not to leave a tick in front of “Xtreme burn-in”. If you mark this item, then the load on the video card will be just crazy. This is not every customized computer can withstand, and even the usual and standard – even more so.

Before starting the test, be sure to close all other programs, applications, and games. So the stress test will show the best results during the test.
Further we direct the pointer on “Burn-in test” and we make a click.

Before the final start of the stress test, the program will once again remind you that the use of the test places the responsibility solely on the user. And additionally informs the list of the reasons causing unstable work of the computer during check:

incorrect settings;
lack of power supply;
poorly working video card fan.

Then click on the loud English word “GO!”:

Now your video card will begin to experience a monstrous load. And the culprit – the animated image on the center of the screen will make the video card work above its capabilities. In its center are concentrated millions of microscopic pixels, which are constantly changing.

Along the edges are graphic “hairs” imitating animal hair or human hair, for example, in games. The background also changes in waveform and makes the graphics card even more stressful.

In the case of a working device, the temperature should stop rising and gain a foothold at a certain point. Usually this temperature is within 90 degrees:

Temperature 90 degrees
More on how to see the temperature of the video card – read here.
And now it’s time for an educational campaign:

A temperature of 90 degrees is peak for any video card, but not dangerous for the equipment (if the test lasts less than 15-20 minutes).
But if the temperature has risen to 100-110 degrees, this is a critical value, and you need to immediately stop the FurMark check. If the system does not respond, use the emergency reset button on the front of the system unit or pull the plug from the outlet (be careful, avoid electric shock).

Try to do everything at the program level, because a sharp lack of power is not useful for the computer.
If you do not stop the program and allow the video card to run on critical heating, it will very soon smell fried. And literally. You will smell something burnt or burned (the probability of a breakdown of the device in this case is 90%), and the computer can reboot.

Moreover, if there is a restart during overheating, this is exceptionally good: emergency shutdowns of the computer help to save the equipment from breakage.
If the video card works stably after checking (no errors happened, there was no overheating, the “donut” on the screen moved smoothly), then your video card can only be envied. After all, its performance is beyond question.

Or your graphics adapter stops responding, and the screen blinks /
The graphics adapter stopped responding
This means that the working capacity of the device is in doubt. It did not cope with FurMark’om, which means, it’s time to think about replacing the video card or preventive maintenance.

Methods for verifying the video card for operability (part 1)

When mastering a computer, many users do not have problems with the equipment. But if the picture deteriorated over time, artifacts appeared, it is possible that the video card should be checked for operability. How you can do this, you can learn from our article. More info you can find here: electronicsrepair.site

Signs of poor performance

Before you sin on the video device, you should make sure that it is in it. It happens that everything indicates a malfunction of the graphics processor, and it was in the transmitted SATA cable. Therefore, we will deal with the main signs of malfunctions, which may indicate damage to the video card, resulting in a drop in performance:

Image on the monitor.

Artifacts are various defects: noise, lines, twitching of the screen. If this happens in the process of working on a computer, it is most likely the case in the video card. The first step is to check the device for operability, but not the fact that it will be possible to do it yourself. Sometimes, the problem can lie so deep that it can not be detected even in the service center (SC). Unfortunately, such cases are not uncommon.

Sound.

Computer hanging can be caused by almost any of its components, however, if the sound loops, this is a plus for the solution, but a minus for the video device. The fact is that if sound defects continue to be heard from the speakers / headphones, then the video card is working poorly and does not cope with its tasks in graphic display.

Any other signs.

All kinds of errors, computer hang-ups and other problems can be associated with any computer component. However, the video card is a device that is always in operation, hence, the probability of its failure is statistically higher. That directly affects the quality of the device.

Video card
Remember: when it comes to the computer, everything is relative. Even if the performance of the video card is not ideal, there are problems, this does not guarantee that its replacement will correct the general malfunction. It is not uncommon for a broken processor in a computer to last another year and even two, and the key difficulty was created by an old cooler.
If there are substantial grounds to suspect a video card of a failure, it is necessary to check it for errors and breakdowns.

Viewing a video card

The first step is to inspect the device. It is possible that you will find some malfunctions on the physical level without going into the software one. Pay attention to:

Swell condensers.

Condensers carry the functions of smoothing the electrical voltage. They absorb the charge when the energy jumps and release it during periods of idle time, when there is not enough energy. That is, they constantly overtake a certain tension through themselves. Their malfunction is only the tip of the iceberg of the reasons why the graphics card can work worse.

We are not in vain digressed into physical malfunctions, since they directly affect the performance of the graphics processor. Even one threaded device can seriously reduce the performance of the video card due to its malfunction.
If the apartment is badly wired or the electricity is often turned off / on, and there are energy jumps, check the capacitors for swelling:

Condensers for swelling
These are standard capacitors. Most often they are located on the motherboard, in the same place and come into disrepair (the motherboard interacts most with voltage, since it feeds all other devices).

But on video cards they are also present and can be called tantalum. A slightly different shape, but a bloat in the event of a breakdown will be obvious.
Another thing is solid-state and fully enclosed capacitors. Outwardly they are indistinguishable, but inside – who knows? To verify the functionality, you can use the device with a multimeter or take the video card to a service center. You should ask to check the devices for leakage or swelling.

Be aware that a comprehensive test of a video card will fly into a pretty penny, or entail a laziness of the masters: rarely will anyone want to check every millimeter of the device. Therefore, you need to contact the trusted SC with a good reputation.
Scratches.

When they are detected on the surface of the device, you must also refer the video card for verification. If an important component is damaged, it will affect its performance, and the reason may be hidden in these same scratches.

Other breakages.

There is no point in further testing the performance of the video card, if it is found cracked, cracked, etc. First you need to eliminate physical damage, but it will be much more expensive than just buying a new device.

All the actions considered must be done in order to analyze the video card. This is the first stage of verification. If there is no damage, then the device will work well (at the physical level).

How to make a computer service

With proper maintenance, the computer runs at higher performance, regardless of the hardware settings and configurations. This article describes how to maintain a computer to improve its performance and extend its life.

Software / Hard Drive

1 Clear all garbage left by browsers. To do this, use the “Disk Cleanup” utility, preinstalled in Windows, or download a similar free program, for example, CCleaner. On Linux, you can use Kleansweep or BleachBit. Cookies and caches can occupy up to gigabytes of hard drive space, so it is extremely important to remove them.

2 Locate and remove spyware and / or viruses on your computer. For this, there are many programs, for example, AVG Anti Virus. You can download antivirus and malware scanners from download.com.

3 Monthly defragment the hard drive to maintain an efficient system operation. Windows includes a utility for defragmentation, but there are third-party programs, for example, Magical Defrag, which automatically defragment the drive during its idle time.

4 Remove programs that you do not use and delete music that you do not listen to. The more free space on the hard disk, the faster it works.

5 In the Run window, type MSCONFIG. A window will open where you can exclude unused programs from the startup. This will speed up the loading and shutdown of the operating system. To exclude programs from startup, you can also use CCleaner (“Tools” – “Startup”).

6 Use the utilities to manage the disks.
In Windows, open Computer Management, and then click Disk Management.
On Mac OS, open Applications, Utilities, and start Disk Utility.

Hardware / Processor

1 Always turn on the computer through an uninterruptible power supply (UPS) to protect parts from electrical problems. The emission limit should be installed on the telephone line; in the opposite case, you run the risk of staying without a modem or network card.

2 Dust covers computer components in less than a year (depending on where the system unit is located). Open the system unit (even if you have a little dust in your house). Check the presence of dust inside the computer case every few months or more if there is a lot of dust in the environment.

Remove dust on the bottom of the cabinet with a vacuum cleaner (or cloth), then blow out the components with compressed air. Pay special attention to the radiator and cooler installed on the processor. When blowing, keep the coolers from rotating. Also blow the cooler in the power supply. When the system unit is open, turn on the computer and make sure that all coolers are working. Replace the cooler if it does not rotate or when it generates unnatural sounds (in this case, you can try to lubricate the bearing).

3 Be careful when connecting USB, Ethernet, speakers, printer, etc. If the connection is incautious, the USB and Ethernet connectors can be easily damaged (these connectors are important, and their repair will cost a lot).
4 Do not overclock the processor; in this case, he will serve a maximum term.

Advice
From time to time, turn off the computer. The computer can work without interruption (for days), but keep in mind that the longer the components are exposed to the increased temperature, the faster they wear out.

Delete only those files that you know. If you accidentally delete an important file, it can lead to serious damage to the system.
Such programs as LimeWire, BearShare, Kazaa provide great opportunities for information exchange, but they contain files containing malicious software. Beware of identity theft or important information.
Be careful when working in the “System Configuration” window (run by the msconfig command). If you do not know which program to remove from startup, do not exclude anything, since you can disable an important system process. Read more on our website: http://electronicsrepair.site/

Be careful when overclocking your computer. As mentioned above, elevated temperatures can spoil the components (especially the processor). When overclocking, take additional measures to cool the components: additional case coolers, a larger cooler and a heat sink on the processor, etc.

There are two opinions. Many people prefer to leave the computer on, since thermal expansion and compression of components with multiple turns on and off of the computer can also lead to components failure. In this case, just turn off the monitor. And set the hard disks off after one hour. After an hour, you can also put the computer into the standby mode (although sometimes this causes the computer to be locked).

If the program is not completely removed, you can delete it manually using Registry Editor (type Regedit in the Run window). Be very careful when working with the registry editor, because in it you get unlimited access to the components of the system. Use the registry editor only if you are an expert! Otherwise, incorrect removal of even one registry entry can cause serious problems.

Quantum chance: how IBM builds an ecosystem for the computer of the future

“For the quantum – the future” – a popular stamp among technology enthusiasts. But for IBM, these are not just empty words, but a well thought out plan. A corporation with a hundred-year history recently lags behind in the race of innovations to smartphone manufacturers, social networks and Internet services. Therefore, the bet on the creation of the first universal quantum computer and the construction of a full ecosystem around the device is a chance for IBM to again become the leader.

And the corporation is trying: Russian and foreign experts interviewed by RBC magazine call it one of the world leaders in the development of a quantum computer. In 2014, IBM announced its intention to invest $ 3 billion over five years in supernova technology, much of this amount will be spent on a quantum project, and in 2017 launched a special unit of IBM Q. From all technological giants who have projects in this sphere, IBM distinguishes the system approach: the company builds a real quantum ecosystem.

Quantum computer IBM is developed in the company’s laboratory in Switzerland. The installation at a height of 3 m consists of several blocks with different temperature conditions, each responsible for its part of the process of quantum computing. Outside – a protective metal casing. All components are sensitive to changes in the environment: even such a trifle as repair work a few kilometers from the computer, can affect the accuracy of calculations.

For effective operation, the installation must be strongly cooled – this is the condition for the appearance of superconductivity, in which the device runs from IBM. At the first stage of the installation, the temperature is only 4K (-269ºC) – colder than in the open space, and close to absolute zero. Here is one of the signal amplifiers emanating from the qubits (q-bits, the basic element for storing information in a quantum computer, RBC), and the microwave control input lines for the rest of the device. This stage is cooled, including for leveling the temperature jumps when interacting with other components.

The second stage is also the input lines, the third is superconducting coaxial cables capable of transmitting a signal between quantum components and a classical computer that controls a quantum system. The cables include niobium and its alloy with titanium. With strong cooling, this material passes into a superconducting state.

Also at the third stage – cryogenic insulators and a mixing chamber, which are responsible for maintaining the temperature. The fourth, last, step is the processor itself and the quantum amplifiers, which make it possible to read the signals of the processor and reduce the “noise” that interferes with the calculations. The processor is in a separate protective chamber – it does not let out electromagnetic radiation, which can affect the qubits and spoil the results of the calculations.

The need for such protection is also related to the specifics of IBM’s devices for working with qubits: they are based on superconducting electronic circuits and use niobium, aluminum and silicon as the main materials. Of the niobium, capacitors are made, aluminum goes to the non-linear bridge connecting the two capacitors, and silicon serves as the basis for the chip. Since the elements of aluminum are several times thinner than the hair, they are subject to any vibrations and radiations.

Superconductor chips are most often used in the manufacture of quantum computers. Other platforms for creating qubits (ion traps, cold atoms) are more common in laboratory projects and are rarely found in commercially oriented solutions.

Problems for 50 qubits

A quantum computer from IBM is a vivid example of the achievements and problems inherent in such modern developments. From competitors, the IBM device is distinguished by the technology of manufacturing processors. On the printed circuit board are placed several resonators, peculiar “road junctions” for light beams. Their task is to provide the maximum coherence time of the system, that is, the time for which the system can perform calculations without data loss. The location of the qubits in the chip on the PCB depends on the number of these qubits.

The main problem of the device, which is also inherent in the projects of all industry leaders, is that it can not perform quantum computing on an ongoing basis (and not just in a short time), and also can not store the results of these calculations. Classify the flaws by using classical systems connected to a quantum installation and creating a kind of hybrid system. Now a regular computer is an integral part of the quantum computer: for binary logic, for example, lasers are controlled and other parameters of the quantum system are monitored. Information obtained as a result of calculations on a quantum device is also interpreted by means of a PC.

In the IBM laboratory, we managed to simulate a 56-Kbit processor, but the company notes that the industry has artificially set itself a limit of 50 qubits and it is not at all the main criterion of the system’s power. Especially since this bar was repeatedly taken and the company D-Wave with its computers capacity of 2 thousand qubits, and most IBM. “The number of qubits does not mean growth as a calculation. Problems that were on five qubits, and remain at 50, “- explains in one of the training videos IBM Research Officer Lev Bishop.

According to the scientist, manufacturers need to concentrate on the quantum volume – a parameter that allows us to evaluate a quantum computer in terms of the number of errors in the calculations. It was suggested by Bishop himself: an increase in the number of qubits without correction of errors, he said, inevitably leads to a decrease in the efficiency of calculations. At the moment, out of 100 operations performed on a 5-qubit processor, one will be erroneous, and with an increase in the number of qubits, the percentage of rejects in computations will also grow, according to calculations by IBM.

IBM hopes to improve the quality of the quantum computer in the coming months. Within the framework of the organization IBM Research Frontiers Institute, the consortium of researchers assesses the possibility of commercial use of technologies, including in the field of quantum computing. Among the founders are Samsung, JSR, Honda, Hitachi Metals and Nasage. According to IBM, a “universal” quantum computer is planned to be launched in 2018.

Based on the IBM Quantum Experience cloud service launched in 2016, which is now used by scientists and enthusiasts for free, a platform is created for which the companies participating in the experiment will pay for access. The service will allow you to optimize business processes in large corporations, use the power of a quantum computer to work on artificial intelligence and so on.

The mass distribution of technology is still limited by the complexity of its scaling: a refrigeration unit capable of 4K, for example, is not so easy to reduce.

Interface in the cloud

In addition to building a universal quantum computer, IBM aims to create a community of developers and users. The PC was also once grounded for the solution of specialized tasks and could foresee its transformation into mass technology units, reminded the company.

IBM regularly releases training videos and demonstrates developments in profile exhibitions, for example in our flickr account – https://www.flickr.com/people/electronicsrepair/

Also, the company was the first competitor to open two versions of the quantum installation for 5 and 16 qubits in open access and plans to present the third one in the near future to 20. The interaction with the user takes place in the IBM Quantum Experience cloud service.

After registration, the user is offered a choice of two types of interface, different in complexity. At the initial level, you can use flowcharts to write simple programs. The basic interface, available in any modern browser, is similar to programs for writing music: the same columns and lines. Place on them, however, suggested commands for the computer. With the help of instructions from IBM, any user can familiarize himself with the basics of the operation of a quantum computer. A more advanced version offers a text editor for programming. To work with the cloud, no additional hardware is required, only a keyboard and mouse. The service also offers a full instruction and demonstration of opportunities.
