High scores seek experts to solve the problem of computer reboot with the right medicine!!

Isn't the power supply fixed by a few screws, you remove it, but because you have no experience with computer cables, you can remove a wire when you remove it and make the same mark on the socket and plug. In case of disorder. However, it is generally well plugged in, and it can't be plugged in the other way.

Unplug it and then disassemble it, don't be afraid, anyone has a first time. Use a brush to clean up the dust and put it back on.

Poor heat dissipation of the power supply will affect the performance of the whole machine.

If that doesn't work, you'll have to think about something else.

There is generally a cooling fan on the graphics card, see if it rotates normally, whether it rotates fast enough, if not, check whether the power supply plug of the graphics card is plugged in firmly.

If the problem persists, is there a problem with your computer's display settings, the display refresh rate is too high, or the resolution is too high, how about trying the protected mode to start? If the protected mode can be activated, first fully disinfect the virus, and then reduce the resolution.

If the virus is at work, find a new version of the Rising antivirus CD, let the computer boot from the CD, use the disc to kill the virus under DOS, or reinstall the system, the first thing to do is install the antivirus software to kill the virus.

Change the refresh rate to make it a little lower.

Find a graphics card and try it.

Try a different memory module.

Identifying problems with substitution is the most commonly used method of problem diagnosis.

The CPU is overheating, change the fan. The probability of this power supply is very small, and the graphics card generally does not restart, under normal circumstances, the reboot is either a problem with the memory, or the CPU is overheated, and the CPU heats up very quickly. In a few seconds, it will reach 90 degrees.

Memory corruption is not necessarily an alarm, and it may not be necessary that the starting part is broken. If you're really worried about the power supply, borrow one and try it.

Pay attention to the CPU temperature when using, clean up the dust in the power supply, try to change the graphics card or change the power supply test, there should be no big problem!

It's obviously a graphics card issue!

See if your graphics card's fan can work properly first!

Is there a problem with your signal line, it's hard to say anything else, you test the graphics card, if there is no problem, the signal line is faulty!

The computer can't be turned on, the monitor doesn't respond, there must be a problem with the computer hardware, it is best to use the replacement method to eliminate the problem, judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

In this case, the indicator light may be damaged, or the laptop has no indicator at all.

It shouldn't matter what I told you. That's a problem with the system files. Now you've reinstalled the system.

1.Verify the disc problem, take it to another computer to read the disk and verify, there should be no problem.

2.Verify the problem with the hard drive, remove the hard drive, and attach it to another computer. The original hard disk of this computer is still used as a boot disk, and after starting, see if you can recognize the drive letter of the newly attached hard disk.

3.If the second step can't be done, just take the hard drive off, connect it again, remove the memory, put it back on, take off the CMOS battery, and discharge it for one minute (the coin cell battery on the motherboard). BIOS LoadDefault, reboot and see.

I have encountered a situation where the boot wind is dissipated, but the system does not start, and the CMOS discharge is fine, the reason is unknown.

If the BIOS can't detect it, it's a hard drive problem.

Or did you choose the wrong hard drive mode, is it SATA?

What brand of computer do you have? In the BIOS Config configuration, find the stat configuration like Change.

Take out the motherboard battery and reinstall the system.
