The desktop computer kept restarting, the CPU was useless after changing the power supply, and the g

Solution: 1 Check whether the antivirus software has killed the virus, you can determine, whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use a variety of antivirus software combination to kill the virus, or if it doesn't work, reinstall or restore the system, you can solve it.

2 **Computer Manager hardware test, test the temperature of each hardware of the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and change the CPU fan.

3 If the computer has a discrete graphics card, the power supply is not enough, then you can only change to a higher power power supply, the power supply has been used for a long time, unstable, then you also need to change the power supply to test.

Follow the steps below to troubleshoot:

1. First, check whether the CPU fan, graphics card fan, power supply fan, etc. are slow or stopped, causing problems caused by high internal temperature of the computer.

2. Check whether the power supply is insufficient, whether the power output is stable, and replace the power supply test, if the power supply is changed, it will be normal, and the power supply is damaged.

3. If the power supply is still the same, consider reinstalling the driver of the hardware on the system, it is recommended to install it with a random driver disc or install the driver on the official website**, if it is not possible, consider that there is a problem with the computer system, first reinstall the original operating system.

4. If you reinstall the system, you need to further check the motherboard, memory, hard disk and other hardware, and use the replacement method to determine the faulty hardware, and replace it.

1 The power strip is not in good contact.

2 Computer power supply problems, power supply aging performance decreases.

Because of the summer, the outdoor temperature itself is high, it is recommended that you open the lid of the case and run for a period of time to see if it is still restarted, if it is relatively stable, it means that it is a problem with the temperature, if it is still restarted, it may be a hardware or system problem, it is recommended that you change the system to see, if the system is still restarted after the change, then it may be your power supply is insufficient!

It may be a problem with the hard disk, or a problem with the system, 1 hard disk bad sector is the culprit of the more common crash, the hard disk may produce bad sectors after a long period of use, you can use slow format to shield, 2 system problems, the use of an unstable system (inferior pirated system, excessive optimization of the system or something), or the system is damaged (virus, software conflict or something), are and may cause crashes, use genuine or original system, do not go through excessive optimization, All optimizations come at the expense of system stability, pay attention to virus protection, and use a reliable antivirus (don't think that you can use it just as an antivirus, especially since the quality of free antiviruses is uneven, and some of them are like viruses).

Hope mine is helpful to you.

The memory module is unstable and often freezes.

In addition to the above, the graphics card and the surrounding wave capacitors, as well as the memory and surrounding resistors and capacitors, can also cause crashes, a little more.

This blue screen shows that the operating system has crashed.

There are several main reasons that you can check one by one:

1.Microsoft windos7 patch has recently had a bug, easy to cause a blue screen, if you have recently updated the patch, then look for a detailed solution online.

2.Software conflicts, such as having several anti-virus software installed.

3.Virus intrusion, the system kills several times.

4. Hardware failure, such as sudden damage to the hard disk, memory corruption, unreadable.

It may be that there is a problem with the hard drive, and you repartition and reinstall the system, which may shield the bad sectors.

When I first turned it on, did it show English with white letters on a black background? If it is displayed, it means that the hardware problem is not very likely, reinstall a system, even if your current system is repaired, it is not easy to reinstall.

If there is no signal on the monitor, it is recommended to change the memory. If there is a display (including a blue screen), it is highly recommended to reinstall the system and solve it perfectly.

There are two possibilities: 1. The CPU temperature is high 2. The system has a virus.

Solution: 1. Replace the exhaust fan 2. Reinstall the system.

Go to the repair shop and take a look, the motherboard burns and you can't do it.

There are more CPU fan thermal conductive glues.

The CPU or graphics card is too hot, and it's basically a broken fan.

I'll break it down:

1.First of all, this temperature is not high in summer, it is a normal temperature, and it mainly depends on how much your room temperature is.

2.With such a configuration, the 250W power supply is enough, and if the power supply is genuine, there should be no problem.

3.The reason is probably the cooling fan of the power supply, you used to be the Great Wall 380 power supply, this power supply has a huge exhaust fan, which can bring the heat of the power supply and accessories to the outside of the chassis in time to ensure that the chassis has cold air in time; And your miscellaneous power supply, it is estimated that the fan speed is slow, and the size is relatively small, so it can't take the heat away.

It's not very simple.,Take a power supply and try it again.,The main thing is to clean up the inside of the computer.,Change the processor to the depression.,Don't have too much,

There may be an abnormal power supply voltage or a place where the computer hardware is in poor contact.

Hello: You take a look at the silicone, it is recommended that you change to a new silicone and try it!

Reboot failures don't happen for no reason, right, what did you do before restarting? What hardware has been upgraded? You can talk about it in detail.

1. There may be incompatibilities between systems or programs, and it is recommended to restore the system or reinstall it.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. Power failure and voltage instability can also cause automatic restart.

4. Incompatible drivers can also lead to restarts.

5. Failure of motherboard parts.

6. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the checkmark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

If the reinstallation system is ineffective, it may be caused by a hardware problem, and it is recommended to overhaul it.

Go to the Device Manager and check if there are any conflicting places with the various drivers, and if there are any yellow ones! If there is a possibility that the device driver is incompatible with the system; Then delete the drivers of the card, graphics card, network card and other devices, and then install the drivers one by one, restart the computer every time you install a device, to check which device's driver caused the failure, find out, ** the new version of the driver of the faulty device, and then install it. Then clean the dust in the computer, clean the memory, graphics card and other devices, and reinstall the memory and other devices.

Unplug the memory and graphics cards and plug them in again, clean up the dust and take a look.

Generally, it is a problem with the memory module, you can take off the memory module and wipe the gold finger clean with an eraser before installing it.

Replace the memory, if it still doesn't work, it may be a motherboard problem.

Whether the boot is normal, check if there is a problem with the hard disk...

Check first in the following order:

1. Check whether the system wiring, especially the external power supply socket of the graphics card is plugged in (if any), and whether the 4-pin power supply of the CPU is plugged in.

2. If there are more than two RAMs, unplug one and leave only one on each RAM slot.

3. Clear the COMS of the motherboard, or unplug the motherboard battery for a few seconds and then install it.

4. Unplug the graphics card and memory, clean the gold finger of the graphics card (including the memory), and erase the oxide layer on it with an eraser. Fold a piece of A4 paper into a triangle and tuck it into the PCIe graphics card slot and the memory slot and wipe it back and forth a few times.

5. If there is a centralized display, unplug the independent graphics card and use the integrated graphics card to start it.

Sixth, the power supply aging.

Seventh, none of the above can be done, most of them are hardware failures. Directly get the merchant who bought your motherboard and ask the merchant to help you solve it.

If there is a problem with the power supply, you check the wiring and unplug the useless first.

You buckle the BIOS battery of the motherboard and wait for 5 minutes to install it to see if it can be solved.
