After the computer crashes, it will be a black screen when it is restarted

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;

Faults such as computer failure to turn on, freeze, black screen, blue screen, restart, and stuck operation can be 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 can listen carefully to see if the CPU and graphics card 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 display); 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. Reminder, if the fault persists after reinstalling the operating system and it is confirmed that there is no virus, you should consider replacing the operating system disk and trying again. In addition, after the system is installed, it is best to complete the patch before using it; to reduce the threat of viruses.

The common causes of a black screen are: one, the power supply chip is damaged, two, memory problems, and third, BGA (graphics card. North and South Bridge) is caused by the virtual soldering of the packaging chip, and there is also a situation where the screen is dark faulty, and many netizens think that it is a black screen phenomenon. It is recommended that you send it for repair.

I can help you in Beijing.

If you are not in Beijing, it is recommended that you find a reputable and skilled repairer to help you overhaul.

It is usually caused by system reasons and hardware failures.

Solution: 1. Press F8 when you boot up, and select "Last Correct Configuration" to try to repair.

2. Press F8 when booting up, and select "Safe Mode" to try to repair.

3. If method 1 and 2 cannot solve the problem, repair the system through system restore or reinstall the system.

4. The above cannot be solved is hardware failure, after-sales inspection and maintenance.

First of all, now that it's hot, you need to have a cooling bracket ready.

Ventilation should be good. It's almost time for the laptop to boot up.

It needs to be turned off.

In that is, you now have to check if your laptop's fan is spinning.

There is something wrong with the hardware.

It's not something that can be done with a reinstall system.

Isn't it that you've been playing games for too long, and the laptop is too hot.

The automatic shutdown of the computer is mainly caused by the following reasons:

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.

Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

Talking about the problem of destroying the source. The lack of power supply is also an important factor that causes the computer to automatically shut down, but from this configuration, the potato moldability of this problem is very small.

Software factors. 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.

5.Hardware resource conflicts. It is common for the settings of the sound card or display card to conflict, causing an exception error.

In addition, interruptions from other devices, DMA, or port conflicts may cause a few drivers to panic. The solution is to start in "Safe Mode" and make appropriate adjustments in "Control Panel" - > System - > Device Management".

The computer shuts down automatically for no reason.

Suggestion: Reinstall the operating system first to troubleshoot system issues; Check the settings for CMOS power management; If the CPU fan does not have enough heat dissipation capacity and the CPU temperature is too high, the automatic protection function of the CPU and motherboard will automatically shut down without any reason. power failure; Or the power supply of the host is faulty, and the voltage fluctuates greatly, resulting in irregular automatic shutdown or restart.

Or the voltage of the external power supply is unstable, and the stabilized power supply can be added.

Hello, I'm glad to answer for you, I hope it will be helpful to you.

There are many reasons for the black screen, one is caused by a virus, try the whole antivirus, the second is a system problem, or there is a conflict between software and hardware, and the system can be solved by reinstalling the system, and the third is a problem with the graphics card, the graphics card driver is wrong or the graphics card is broken or the graphics card is loose.

Clean up the dust under the chassis, wipe off the gold finger of the graphics card with a skin like skin, and see if it is magnetized, 4 hardware problems, for example.

Memory module CPU

Graphics card motherboard. and so on, whether there is looseness.

5 Monitor Issues.

The monitor is broken.

6. The hardware acceleration is set too high and exceeds the frequency range.

Click Windows Start Menu - Control Panel - Double-click the Show --- Troubleshooter tab, and under Hardware Acceleration, gradually drag the slider from Full to a position close to None-click the OK button.

The 7BIOS settings are incorrect or the overclocking is unsuccessful.

Caused by a black screen.

It is possible to reset the BIOS settings to their default values by discharging the motherboard.

8. The screen is black when the program is opened, for example, the game, one is that the graphics card does not meet the requirements of the game and is black, and the other is that it conflicts with the program, so it is black and crashes.

9 hit Microsoft's black-screen plan.

It is recommended to reinstall the system.
