When the computer is turned on, it will be stuck here for about 30 seconds

If you install a certain software, the software will start by default. You can take a look at your boot items. Selective startup. Ban it and you're good to go.

Press the tab button to see what the system is doing behind the logo? Transcribe the message before asking questions.

It takes a long time to read the hard disk, because it needs to be loaded after the self-test is completed.

Check the boot item, and if it doesn't work, reinstall the system.

Or there's a virus, take your host computer to repair the computer, and my house is the same.

Press F11 or F12 to select the drive mode

2. Setting problem: BIOS settings, you first set BIOS to the default settings. Right-click on my computer's properties, find the "Restart if there is a problem" option, and uncheck it. The system settings were confirmed to be fine, too.

3. If the heat dissipation performance is not good, it may automatically restart. But this is unlikely.

4. Power supply problem: The phenomenon of insufficient power supply may also lead to restart, you can change someone else's power supply to try.

5. Software problems: Some software itself has problems, and you can change the software.

6. Driver problem: The driver is not installed or the correct driver is not installed. Just uninstall and reinstall.

1.If it's full, the machine will still crash, most of which may be a hardware problem; Did your computer boot up and enter the desktop? When you turn it on, press F8, select the heavy security mode to start, go in and see if it will crash immediately, if the problem is still the same, you can judge that it is the hardware reason;

2.Open the lid of the case, clean the machine, especially the CPU fan, and replug the memory and hard disk cables.

3.The hard disk has bad sectors, and when there are too many bad sectors, it cannot be repaired;

Mind reinstalling the system, if not, you see if your hard drive has bad sectors. If there are bad sectors, use special software to see if they can be repaired!

Supplement, see if there is silicone under the CPU fan, if not, go buy some and wipe it on, it may be caused by poor heat dissipation, if it doesn't work, it may be a problem with the hard disk.

The problem with the hard disk may be that your memory is not enough, and the software may be that your system has too much junk or poisoning That's it, if you have a hard disk, spend a few hundred yuan to buy a second-hand memory, which is very useful

Reconnect the hard drive cable on the hard and soft sides, unplug the optical drive cable, and then turn on the machine to see.

Is it because of poor heat dissipation?

Consider the following questions.

1. CPU fan heat dissipation, if the heat dissipation is poor, it will slowly feel very stuck after turning on for a while, and it will even crash if it is serious, and it will automatically restart. You can check the temperature of the CPU in the CMOS. Above 50 degrees, there is generally a problem.

Second, the virus is caused by the virus, when you turn on the computer, the virus starts to run and drains your memory.

If the virus doesn't get rid of it, try reinstalling the system.

You have Lu Dashuai to test whether the temperature is high, if the temperature is high, it will be stuck, or there is a problem with the CPU fan, and it will be hot after turning on for a while, so it will be stuck, crashing and other phenomena.

The CPU heat dissipation is not good, take the fan down and clean it, and put oil on it. The gold finger of the memory module is rubbed with an eraser.

It should be very deeply poisoned, and the general reloading is not good, so it is recommended to check it all!
