What should I do if the computer restarts as soon as it is turned on, and then restarts when it is f

My computer also has the same problem.,After turning on, press F8 to select and enable your last correct configuration,That's it.,If the next boot is the same, you can only try the following method.。 This is also the answer given to me by a friend, and I think it should be possible. I just don't have a CD.

Generally, the reason for this error is that the files are missing or corrupted. The workaround is to re-extract a new file from the disc of Windows XP with Windows Recovery Console, here are the steps:

1.Start the Failback Console.

2.In the command prompt, type "cd system32" and press enter.

3.Enter "ren kernel132,old" and press enter.

4.Enter "map" and press enter.

5.Pay attention to the drive name of the optical drive where the Windows XP disc is placed, for example, "F:", and replace it with your actual optical drive letter when it is actually used.

6.Type in "expand f: i386" and press enter.

7.Type "exit", and when the computer is actually removed, take out the Windows XP disc and let the computer boot normally.

Hello friends:

The main reasons and solutions for the computer to keep restarting are as follows:

The first reason is: the general computer has been restarting, 60% of the host power supply problems, when the power supply filter capacitor bulging and leaking, resulting in insufficient power supply, it will form a computer automatic restart.

Solution: Replace the power supply of the host.

The second reason is: there is a problem with the CPU fan on the computer, or the clip of the heatsink is loose. When the CPU fan is stuck or broken, causing the CPU to not cool down, when the temperature reaches the set temperature of the motherboard, the motherboard starts the self-protection function, and then restarts, or when the CPU heatsink card is loosened and turned on, the CPU detects that there is no heatsink to cool down, and immediately stops working and cuts off the power supply, so it will automatically shut down and restart after a few seconds, and restart repeatedly.

Solution: Jianyi replaces the CPU fan, or because the ash blocks the fan, just get the fan through. If the heatsink clip is loose, then just reinstall the clip and add some silicone grease to the CPU.

This is all to cool down the CPU, only the CPU can ensure the normal use temperature will not automatically restart repeatedly.

The third reason is: the graphics card's video memory integrated block is soldered, resulting in poor contact with the motherboard after power-on, it will automatically restart.

Solution: It can be solved by soldering the video memory, or changing the graphics card.

The fourth reason is: the voltage is unstable, that is, below 170V, higher than 240V, if the starting voltage is not reached and the specified voltage is exceeded, the computer will be restarted.

Solution: Jianyi buys a UPS, also called an uninterruptible power supply, so that it can not only stabilize the voltage, but also have 30 minutes to save the data time, the fifth reason is: the motherboard's boot circuit has a problem, such as CPU power supply, reset, clock, MOS tube problems, will lead to repeated restarts, and can not be turned on, processing method:

Jianyi can repair the motherboard.

The sixth reason is: the computer poisoning destroys the boot area and the system, and the boot area cannot be found when the boot is turned on, so it will naturally restart repeatedly.

The solution is to repair the boot area and reinstall the system, (or a one-click restore). There is another point to do, which is to restore the BIOS to its factory value, or you can discharge the BIOS (that is, open the case, remove the motherboard battery, wait for 10 seconds and then press back to the motherboard, I hope it will help you, I wish you happiness
