Why is it that my computer starts up after a while when the computer is turned on for a while, and t

If you try not to go online, will it be restarted, if it will, it will be a hardware problem, if not, it will be in the middle of the horse, and the system will be reinstalled.

Try not to get back up when you don't go online.,If not, it's a Trojan.,Press one key to recover or kill the Trojan!

Your QQ has been hit by a Trojan horse!

Kill with anti-virus software!

I also encountered this situation, and later replaced all the jumper caps on the motherboard to solve the problem.

If the computer turns itself on the next day, and the time is not right, there may be the following possibilities:

The computer's BIOS battery is low. A computer's BIOS battery is a small battery that stores the computer's basic settings and time. If this battery is low, then the computer may automatically reset the time and turn on automatically when it starts.

The computer has the Quick Start feature turned on. Some PCs have Fast Startup, which puts your PC to sleep when it's shut down, speeding up the next startup. If you enable this feature, your computer may automatically turn on and reset the time.

Viruses or malware on your computer. Some malware or viruses may install scheduled tasks on your computer to boot your computer without permission. At the same time, these programs may also modify your computer's time settings.

To solve this problem, you can do the following:

Replace your computer's BIOS battery. If your computer's BIOS battery is low, you may want to consider replacing it with a new one.

Disable your computer's Quick Start feature. If your PC has Fast Startup turned on, you can disable it to prevent your PC from starting up automatically.

Run antivirus software to scan. If there is a virus or malware on your computer, you can run antivirus software to scan and remove it. It is also recommended to run antivirus software frequently to ensure the security of your computer.

Time problems are generally caused by the following 3 reasons.

1. The motherboard battery is used up.

Because system time is stored in the BIOS chip, the BIOS settings must be battery powered to store effectively. Once the battery runs out, your BIOS settings, including the time settings, are forgotten after the power off. Once the computer is turned on, the BIOS automatically becomes the initial setting.

The solution is very simple, buy a coin cell battery to replace the motherboard.

2. Computer virus infection.

Nowadays there are many viruses that can automatically modify your system time, if your system time is not automatically changed after shutting down, but will also be automatically changed during the boot process, then you should be aware that a virus may have infected your computer. It is recommended that you ** antivirus software, and update to the latest virus database version, and scan the system for anti-virus.

3. Software bugs

Recently, there is a USB disk detection and killing assistant, which will automatically modify the system time after use.

1.It's time to change the battery of the computer motherboard, change the battery, 2Turn on the computer without pressing the del key, set the BIOS, restore the default settings to save and exit, select load optimized defaults, F10 save and exit.

3.Turn on and press del without stopping, enter COMS, [Standard Coms Setup] -- find the last halt on: errors and select no errors".

The computer won't turn on the solution:

1.Check whether the monitor and the main unit cable and connector are connected;

2.If the external monitor sees that the system has started normally, then you can check whether the switch button above the keyboard for turning off the power supply when the display is closed is normal;

3.If the external monitor and the pop-up display power-off switch are all right, the display cannot be displayed, then it may be a system problem;

4.If you are unconditionally connected to an external monitor, please reboot it and pay attention to whether the display screen is black at the beginning of the system boot in the DOS boot state. If the screen is also black when the DOS boots, and there is no normal self-test sound, it is mostly a system failure;

The startup disk may be set up incorrectly. Solution: Modify the hard disk mode. Boot up, press F2, F10, F12 Delete (depending on the motherboard) to enter the BIOS, and set the first boot disk as a CD, floppy disk or U disk to a hard disk (harddisk);

6.HDD MBR error can be reset with DiskGenius;

7.Check whether the optical drive, USB flash drive, floppy disk, etc. are inserted, if so, you can take them out and try to turn them on; Keep an eye on it.

8.Enter the BIOS, modify the hard disk mode, set different modes and try to restart to see if it can boot;

9.Press F8 to enter the mode, and select the latest correct configuration or normal startup.

10.If none of the above methods can be solved. Please disassemble the chassis, unplug the hard disk cable and reconnect it, and then see if it can be started; During the boot process, pay attention to whether the rotation of the hard disk is normal under the training leakage and touch it with your hands;

11.The one-size-fits-all approach: reinstall the system.

Try cleaning the case out of dust.

For restarting, tell me about my workaround:

My desktop has been automatically restarting from time to time for two or three years, during which I have read a lot of online lesson plans, from various software conflicts to various hardware problems one by one, which is very annoying, but in the end, it is completely solved from the following aspects:

1. Because the hard disk always has abnormal noise, it is suspected that there is a problem with the power supply voltage, after measuring the power supply voltage, it was found that the 12V voltage output is, and then two diodes were stringed, the model is FR157, so that the voltage drops to, I think it is better to be lower, which is beneficial to the life of the hard disk. After this treatment, the abnormal sound of the hard disk is gone, but it is still restarted.

2. I suspect that there is a problem with the motherboard, so I bought the same motherboard from **, and restarted it after replacing it, which ruled out the problem of the motherboard.

3. Finally, if you suspect that the memory is unstable, you can buy a memory module and replace it, and everything will be fine, and it has never been restarted. So it seems that the main reason for my computer to restart is memory.

This afternoon my other laptop encountered another virus that caused it to restart, and it restarts frequently from time to time. It's time to throw away the old machine, and it's also been rectified! They're not boring! After Ghost recovers the system, everything is fine Hmph!

Go to install Kaspersky, the official version is free for 1 month.

Non-software reasons, it is a hardware problem, but there are many reasons, now the weather is hot, most likely the CPU temperature is too high, see if the CPU heatsink is too dusty.
