The black screen problem in computer screenshots may be caused by a variety of reasons.Here are some common causes and solutions:
1. Graphics driver problem: First, check and update your graphics driver.You can find the display adapter in the Device Manager, right-click and select Update Driver.If updates are available, install them and restart the PC.
2. Hardware acceleration problem: Try to disable hardware acceleration.In Windows, right-click the blank space on the desktop, select Display Settings or Screen Resolution, enter Advanced Settings, and adjust the hardware acceleration to the lowest level.
3. Third party software conflict: some third-party software may conflict with the screenshot function.Try to close other running programs and take another screenshot.
4. High contrast mode: If you use the high contrast mode, the screen will be black when you take a screenshot.Turn off high contrast mode by pressing "Shift"+"Alt"+"Print Screen".
5. Operating system error: Sometimes there are some errors in the operating system itself or corrupt files that cause the screenshot problem.In this case, it is recommended to repair the system or reinstall the operating system to solve the problem.
6. Screenshot tool problem: If you use a third-party screenshot tool instead of the default shortcut key to take screenshots, try changing another screenshot tool or upgrading the software version.
If none of the above methods can solve the problem, it is recommended to contact professional technical support personnel or consult computer maintenance experts, who can provide personalized help and solutions.
The program on the display automatically stops and then resumes. It's no other meaning, but it doesn't mean it's OK, it may be poisoned, or it needs to update the program
Computer black screen is a relatively easy phenomenon, especially in some older computers or assembly computers.There are many reasons for the failure of the black screen of the computer, such as damaged monitor, damaged motherboard, damaged graphics card, poor contact of graphics card, damaged power supply, damaged cpu, etc.The black screen of the computer is basically handled by a combination of exclusion and replacement, and the principle is to replace and exclude the most suspicious parts first.For ordinary computer users, their professional knowledge is insufficient, so the following steps can be taken to analyze the cause of the failure, so that they can eliminate the failure by themselves. First, check whether the contact is good.Check whether the contact between the graphics card and the display is good, and whether the contact between the graphics card and the motherboard I/O slot is good. If necessary, remove it and reinstall it to ensure that it is installed in place and has good contact. If there is no problem with the contact, it is better to try another display to make sure there is no problem with the display. If there is no problem with the display, check whether the cpu fan is running. If it is running, use a multimeter to measure whether the voltage output is normal at ± 12V, ± 15V. If it is not normal, try changing a power supply. If the black screen still appears, take out the components installed in the computer, leaving only the cpu, graphics card, and memory module, and then limit the fault cause to the cpu, motherboard, and memory.Generally, if there is a memory failure, there should be an alarm sound.If the memory fault is eliminated, only the CPU and the motherboard are available. Replace with a normal CPU (which should be compatible with the computer being tested), power on and retest. If the black screen still appears, only one motherboard can be replaced, and the problem should also occur on the motherboard. The black screen fault of the computer may indicate that there is a serious problem with the computer. It may be better to eliminate the black screen problem according to the above methods.In the process of handling, the exclusion and replacement methods should be flexibly applied, and the timely phenomena should be excluded
