How many seconds does the computer automatically restart when it turns on?

Rebooting or shutting down for no reason, generally the CPU is too hot, viruses, dust, bad power supply, bad memory, too hot graphics card, and bad motherboard capacitors.

Enter msconfig in the start menu run, remove all (except ctfmon) checkmarks in the startup and try to save and restart (you can speed up the startup), generally you start the run too much, or file conflicts.

Install 360 security guard, boot has been pressing F8 to enter the safe mode to check and kill, now nine out of ten poisons on the Internet are Trojans, so the antivirus software can not detect the virus, it is recommended to install 360 killing, the heat dissipation is not good, reinstall the CPU heat sink, you can have poor contact, you can replace the CPU fan.

Reseat the graphics card and memory card, the main thing is to clean the dust near the CPU and memory, it is easiest to do this, or try to change the power supply (check your power consumption, sometimes the voltage is unstable).

There are only two possibilities in this case. One is that your computer's power supply is down. Another is that the motherboard of your computer is broken, and the capacitor is burned. And it takes a lot of burns to cause this problem.

Kiss. For this problem, you can consider unplugging your USB flash drive first. Restart your computer and try it again!

If it still doesn't work! It is advisable to check the memory slots on the motherboard! See if the firing pin in the slot is normal, or not, take it to the professional who repairs the computer to check it, thank you, I hope it can help you!

Usually the motherboard is faulty or the power supply itself is faulty.

This situation is usually due to a faulty motherboard (damage, short circuit, etc.) that causes the ATX power supply to protect itself and not work, or the power supply itself is faulty and does not work.

Recommendation: In this case, it is best to replace and test with a normal power supply.

Estimate the following.

1. The power supply is old and the power is insufficient.

2 The radiator fan or the radiator itself has not been cleaned for a long time, and there is dust that causes obstruction.

3. The computer motherboard is damaged and needs to be repaired or replaced.

4 The motherboard battery is dead and needs to be replaced.

5. Replug the memory or check the gold finger with an eraser.

The possible causes are as follows: 1If the power supply is insufficient due to aging, you can first rule out whether it is a power cord or a plug-in fault, if there is no problem, please replace the power supply with a larger power supply.

2.Poor heat dissipation inside the processor, graphics card, or chassis cleans up the dust on the heater. 3.

Check the memory and graphics card cheat part for oxidation, and if so, wipe it with an eraser. 4.Check if the CMOS battery on the motherboard is running out of power, and try replacing the battery.
