On the issue of the black screen of XP on the 20th

I haven't tried it, I just know that now my system must have turned off automatic updates, otherwise it will be completely denied.

Fortunately, my computer didn't wait for the master to crack it.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard.

A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded.

1) The monitor is powered off, or the monitor data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break;

2) There is no power supply to the motherboard;

3) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

6) The machine is infected with CIH virus, and the BIOS is refreshed destructively;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

The main thing is that there is an error, it may be that the graphics card drive is not suitable, and sometimes it is done by abnormal shutdown.

Don't you understand what you mean.,Can you talk about it in detail?。。。

System problem now! If it's not difficult to redo the system, let's redo it!

1. The hardware acceleration settings are too high.

Hardware acceleration can make software that processes a lot of graphics run more smoothly, but if your computer's hardware acceleration is set too high, it can lead to a "black screen" phenomenon. To resolve the "black screen" glitch, try to reduce the hardware acceleration first.

1. Click the Windows Start menu, click Control Panel, and then double-click Display.

2. Select the "Troubleshooting" tab, and under "Hardware Acceleration", gradually drag the slider from "Full" to a position close to "None".

3. Click the "OK" button.

2. Disable 3D acceleration or upgrade the graphics card driver.

If Windows has configured 3D acceleration but the graphics card does not support the feature, then a "black screen" glitch may occur when running games or multi-** programs.

1. Click Start, then click Run, then type DXDIAG in the Open box and press Enter.

2. Select the "Display" tab and click the "Test Direct 3D" button under "DirectX Features" to get the correct Direct 3D functionality.

3. If there is no rotating cube on the screen, the watch card does not support 3D acceleration. At this point, click the "Disable" button after "Direct 3D Acceleration" to disable the feature.

If your graphics card does not support 3D acceleration, in addition to disabling the feature, you can contact the graphics card manufacturer to update the driver to support 3D acceleration for DirectX.

3. The driver of the graphics card is not compatible with the graphics card.

The DirectX installer may incorrectly detect the graphics card and install drivers that are not working properly, so please confirm that the correct graphics card drivers are being used.

1. Click "Start", then "Control Panel", and then double-click "System".

2. Select the "Hardware" tab, click the "Device Manager" button, then click the "+" sign in front of "Display Card" or "Display Adapter", then right-click the display adapter under it, and then click the "Properties" button.

3. Select the "Driver" tab and click the "Driver Details" button to display the graphics card driver used. If you're using a driver that's not compatible with your graphics card, in the Drivers tab, click the Update Driver button, and then follow the on-screen instructions to install the driver for the new version of your graphics card.

The PC boot acceleration optimization is a bit too much and nothing happens.
