The wn7 desktop computer has a black screen, the screen has a mouse display, and Ctrl Alt Del is not

Win7 boots into the desktop black screen, there is only one mouse, the reason and how to deal with it:

The computer boots up with a black screen and cannot enter the system, reason:

1. System failure, resulting in inability to enter the system;

2. The monitor cable is not plugged in tightly or damaged;

3. There is a problem with the display;

4. Graphics card failure;

5. The hard disk is wrong and cannot read the system.

Solution: 1. Reinstall the system (before reinstalling the system, be sure to back up important data in advance);

2. Plug in the monitor cable tightly, if there is a spare cable, it is recommended to replace the spare cable and reconnect it;

3. Replace a monitor and reconnect it for testing;

When your computer has such a situation, don't operate blindly because you are in a hurry, because your blind operation may cause the system to completely collapse, and there is no room for recovery. So, first of all, think calmly about whether you have done anything before, or what you have browsed. Because this situation is likely to be caused by a virus, the virus deletes your system's partition table or system boot file, and such a problem may occur.

We first have to reboot it, keep pressing the F8 key when you turn it on, if you keep pressing it and then a black background and white text menu appears, then fortunately, it means that your system is not in trouble. We enter the safe mode of the system, after which we enter the antivirus and repair the missing system files. Then reboot the machine, maybe the problem will be solved smoothly.

If you keep pressing F8 and nothing happens, it means that the problem with the computer is more serious. If you have a backup of your system before, there may be a chance to survive. Reboot,I kept pressing the up and down keys of the keyboard before turning it on,If a system selection menu appears,It means that the problem is still not big,It's just a system problem,Not a hardware problem。

Select Enter Restore to perform a system restore. After the restoration, of course, it can be turned on smoothly.

If you can't wake up the black flasher interface no matter what key you press, the problem is terminally ill. At this point, it cannot be concluded that it is a hardware problem, and it may be possible to solve it through software operation. This is where you may need a PE system.

Reboot, enter the BIOS, select the USB flash drive to boot, and enter the PE system. After entering, fix the system problem, or antivirus, or repair. After the repair is completed and the computer is restarted, the problem may be solved.

If you enter the PE system, also restore the system, or even reinstall the system in PE, but it is still like this after booting, you should be mentally prepared at this time. Because it's probably a hardware issue. But at this point, it is not enough to send it for repair, you can disassemble the chassis, remove the hard disk cable, memory, graphics card, CPU, and other large hardware, wipe it, and then install it, you must be careful, and you can't violently disassemble the machine because of anxiety, because if you damage a certain hardware, then there is no way.

This is a risky operation, but you may be able to solve the problem by trying. If this is the case, then after you reinstall it, you may be able to reboot the computer and the problem will be solved.
