What s wrong with my computer automatically restarting when it boots up

1. Check the black wire of your power strip (power supply) and the external power supply connected to the case.

2. Check your memory.

3. Check whether your CPU fan is running normally and whether the CPU temperature is too high.

Heat dissipation problems, too much dust in the computer. Clean up the dust.

It is also possible that the capacitors on the motherboard have burned out, check it out. Or find them after-sales.

The most likely reason for this is that the computer has been restarted with a virus, so I don't want to try it with a better antivirus software, because I have also encountered this phenomenon!

Maybe it's a problem with automatic updates, see if your system automatic updates are set to install and restart automatically You can turn this off.

You mean to rule out the problem with your hardware. Don't disassemble the host yourself, or the warranty.

You can reinstall the system yourself to see if it doesn't work, just look for a warranty. Generally, the warranty of brand machines is long.

fainted... It's a simple question...

You go and change the power supply and you'll be fine.

Anyway, your power supply is under warranty.

Hello friends:

Reasons and solutions for automatic restart or repeated restart of the computer after it is turned on:

The first reason is: the general computer automatically restarts, 50% of the host power supply problems, when the filter capacitor of the power supply bulges and leaks, 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, it will automatically turn off the power supply, and then restart, 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). Another point to do 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 to install the machine).

The second reason is a bit larger.

Hope it helps you and I wish you happiness

System file corruption. Overwrite install or reinstall.

1. System file corruption. Overwrite install or reinstall.

2. Viruses. Trojans remotely control all activities on your computer from such as cavity spikes, including getting your computer back up. Remove viruses, trojans, or reinstall the system.

3. Timing software or scheduled task software works. If you set up a restart or load of certain workers in the scheduled taskbar, the computer will start up again when the scheduled time comes.

4. The power supply of the chassis is insufficient, the DC output is impure, and the dynamic response is sluggish. Now replace it with a high-quality high-power computer power supply.

5. Poor thermal stability of memory, chip damage or wrong settings, and the probability of system reboot caused by memory problems is relatively large. Roundsail replacement memory.

6. The CPU temperature is too high or the cache is damaged. In CMOS, the slag is shielded from the L2 cache (L2) or the L1 cache, or the CPU is replaced to exclude.

There are four reasons why the brain boots up automatically or repeatedly. The first type: the general computer boots up and automatically restarts, 60% of the host power supply problems, when the filter capacitor of the power supply bulges and leaks, resulting in insufficient power supply, it will form a computer automatic restart.

Second: 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 be cooled, when the temperature reaches the set temperature of the motherboard, the motherboard starts the self-protection function, it will automatically turn off the power supply, and then restart, when the card of the radiator is loosened, the CPU detects that there is no radiator cooling down after booting, 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.

The third type: the video memory integrated block of the graphics card is soldered, resulting in poor contact with the motherboard after powering up, it will automatically restart. Fourth:

The voltage is unstable, that is, lower than 190V, higher than 240V, and if the starting voltage is not reached and the specified voltage is exceeded, the computer will be restarted.
