My computer keeps restarting after booting up, and I can t enter the system, who knows what the reas

There has been such a virus before, that is, it keeps restarting, and whether the heat dissipation of the machine is not good, because the machine has a self-protection function, that is, when the temperature is high, it will protect itself, you can try it on a bare metal! Or blow with a fan and try again.

1.First of all, remove the dust from the computer, especially the memory, the motherboard. Clean up and put the hardware on firmly.

2.Format all disks and install the system.

3.If there is still a problem, it must be a hardware problem, the motherboard, memory, and hard disk are all possible, and they are eliminated one by one.

Either you have a virus or press F8 on startup, select "Disable automatic restart in case of system failure", and press Enter

Don't be so troublesome, my computer is the same as yours, I guess you also have Kingsoft Poison installed, right?

After entering safe mode, just uninstall Kingsoft Poison!

It's a virus that specializes in Kingsoft Poison, and my computer is ready!

I once plugged in the keyboard and couldn't start.,It turned out to be a memory problem.,It's a memory slot that was replaced.。 You take the memory off and wipe the metal feet on it.

Press F8 to try it after booting,Use safe mode to enter it should be on the line,If not,According to your situation,It's probably the blaster virus on the first floor,Hurry up and take the computer to the repair shop,Or the computer will be scrapped.。

1.: Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.: Memory reasons. When the memory and the motherboard socket contact is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if it is down?

3.: Power supply issue. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

4: Software factor. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down. If you are using Windows

2000 or Windows

XP system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

The computer shuts down automatically for no reason.

5: Check whether the CPU is overheating and whether the CPU fan tray is stable, if it is broken.

Or it is unstable, can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the motherboard's automatic protection function will automatically shut down, and the CPU fan's screws are loose and early!

6: The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

7: When the power supply of the host fails, or the voltage fluctuates greatly, add AC regulated power supply.

8: No, it is recommended to disinfect in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

It's possible that there's too much dust on the fan.

Causes automatic shutdown.

It's normal to clean up the dust!

According to your description, it should be a problem with the operating system, just follow 4; If it doesn't work, it may be a problem on the motherboard, first check the battery of the motherboard; Then check the memory chip, the most common failure is that the content in the EPROM is damaged or lost, and the re-flashing BIOS is invalid, and the chip can only be replaced;

The computer screen is black, or the computer freezes, the operation is stuck and other faults are checked according to the following items:

1. First of all. Check the power supply; 220V AC power supply (plug and socket are usually called); Then check the output voltage of the computer power supply (

Desktop: Check the fan of the power supply, notebook, etc., you can listen carefully to see if the CPU, graphics card, etc. fans in the machine are rotating);

2. See if the computer can "self-test"; If you can self-test, you can generally reinstall the operating system;

3. If it is a black screen, focus on the inspection part (this is all and all the reasons for the black screen of the computer):

cpu；Mainboard; Memory; Graphics; Display (

desktop monitors); Power supply (Yes.)

output, but the supply voltage is incomplete); and the plug-in parts and connecting wires of the above-mentioned parts;

4. Check and remove viruses, reset the BIOS, and reinstall the operating system.

F2 is generally a BIOS setup for some machines. I guess you changed the boot order. It is possible that the "Hard Disk Boot" item has been deleted. Therefore, the computer can only search for startup programs between optical drives, software, and the Internet, and restart if it fails.

Unplug the battery from your motherboard and reinstall it! Go to the BIOS and restore the settings on the motherboard to factory settings!

If you insist that it is caused by changing the BIOS, and you find the relevant items that do not fall, come ruthlessly, disassemble them, remove the electronics from the motherboard, discharge them for a long time, and then install them. In fact, as long as you find a friend who knows how to order BIOS, you can help you turn it back, so you don't have to be so troublesome.

Redo the memory module, it should be that the memory module is loose.

If it doesn't work.

When you start up, you enter the interface of F2 settings, and there is an item in it that restores the default configuration, and then enters the system after restoring. If it doesn't work, it's a system problem, or the hardware is broken.

You need to change the hard disk settings in comc, and then start from the system.

Press F8 after powering on, boot from safe mode, then shut down normally, and reboot on the line.

If the system is not installed, it will naturally restart. Try a different system disk. Also check the repair hard drive by the way.

Reloading with a plate is also a blue screen, and installing it in that position will be a blue screen. It is recommended that you scan the hard drive with MHDD first.

If there is no good answer here, I suggest you go to the home appliance market computer maintenance to see, people are more professional over there, and they will be responsible for accidents, hehe! @
