It is normal after booting on and restarting twice

Fix it.

Or System Restore.

The computer will be restarted after two seconds of booting, and the repeated reboot has not stopped, you can check the circuit board in the chassis, whether the plug-ins are normal, pay attention to the work of unplugging and unplugging, and then plug it back in after wiping, and then turn it on again after power-off. If the problem is not resolved, the operating system should be reinstalled. In this case, the probability of hardware failure is relatively high.

Use the elimination method to solve the problem that the computer can't turn on and restart indefinitely Step 1: First of all, you must know that this has nothing to do with whether the operating system is poisoned. It is mainly caused by hardware (power supply, motherboard, and graphics card), which will automatically restart when it reaches the step of reading the operating system.

The second is caused by a problem with the switch of the chassis. Step 2: Unplug the power cord from the hard drive.

Then test and troubleshoot. Frequent power failures and reboots make the hard disk prone to bad sectors. A small number of such phenomena are hard disk failures (motors or circuit boards), but they should also be placed at the end, confirm other OK first, and then power on the hard disk (in this case, if it is a problem with the hard disk, you will know it at once).

Step 3: Remove the side panel of the case, unplug the switch between the case and the motherboard, and restart the cable. Then connect the two pins of the switch directly with tweezers (there is a definition on the side of the pin, which says power on or pwr on, regardless of plus or minus).

If this is also a fault, you can troubleshoot the chassis switch. Step 4: Replace the power supply and see.

Many of these phenomena are caused by miscellaneous inferior power supplies. Step 5: If the power supply is changed and it still fails, change the graphics card.

Step 6: If the graphics card is still faulty, unplug the memory module and wipe the gold finger with an eraser or alcohol (to remove the oxidation).Then wipe the gold finger in the memory slot of the motherboard.

Step 7: If you have tried all of the above and the fault is still there, it is the motherboard. It is most common for the regulated power supply part of the CPU to be damaged, resulting in a sudden power failure or failure to power on after powering on.

It should be too hot, it could be the motherboard chipset, overheating, or the CPU is overheating, and the memory is in poor contact.

Repeated reboots are most likely due to a power failure, or a motherboard failure. When there is a problem with the memory module, it will also cause repeated restarts. You can check them one by one.

The computer restarts repeatedly, this situation is a motherboard problem, first eliminate the memory module, mechanical hard disk, independent graphics card failure, it is recommended to go to the "computer repair shop" for a hardware test.

According to the subject's description, the most likely is caused by the loss of system files. You can try reinstalling the system. Before installation, use a USB flash drive to boot the PE system, and then back up the important data of the C disk.

It means that there is a problem with your computer system, under normal circumstances, the system problem can only be a redo of the system, or some of your hardware is in poor contact.

1. Generally, there is a problem with the hardware, most of which are memory, hard disks, motherboards, power supplies, etc.

2. Elimination method, change the hardware test.

It could be because of the computer's power supply or because there is a problem with the hardware that is running and you need to restart, for example, because of a boot failure that requires a reboot.

If there is a problem with your computer, take it to the offline service store to repair it! Or see if there is a friend who is more familiar with the computer, ask him to help you check it, and you can also control it remotely.

You'll need to reinstall your computer, maybe the cable inside is loose.

If it is a desktop, you can open the case, directly click on the key cable position to boot and try, if this is still repeated restart, it may be a hardware problem, or you need to check the power supply and motherboard.

If your computer is a desktop, this should not be difficult to solve, you just need to follow the following method.

Open the main case, clean up the dust, and remove the memory card and graphics card.

Wipe the gold finger of the memory card, graphics card, and then install them back and reboot the problem will be solved.

Check the power supply, unplug the power supply on the motherboard and plug it back in firmly, if it still doesn't work, try to change it to a normal power supply.

If the boot is repeatedly restarted, the possibility of hardware is still relatively large, it is recommended to replace accessories to detect the motherboard or power supply.

Because I haven't cleaned the ash for a long time, I changed it with silicone grease by the way, but it was the first time I applied it, and I applied it a little too much, and I put it on and opened it for 2 or 3 seconds and then restarted it repeatedly. Then I reapplied the silicone grease, this time it was thin, but it was still like this. What to do? ...

It may be a system problem or a memory problem, you can check them one by one.
