If it is an XP system, right-click on the desktop and select it in the pop-up display properties dialog box"Settings", enter the settings interface, and then go to the"Screen resolution"Adjust the position and drag to select, adjust the resolution to 1280x1024, and select the color quality"Highest (32 bits)."Then point"OK"

Reboot, when the BIOS boots (black and white screen), is there any abnormality in the screen? (such as distorted, blurred screen or something), if there is, and you have already replaced the graphics card, if not, reinstall the system to see if it can be solved. If reinstalling the system and replacing the graphics card (to ensure that the replaced graphics card is good, and the drivers and settings are installed correctly) can not solve the problem, it is basically a hardware problem, if there is a condition, the same hardware is replaced for testing, if not, then go to a repair shop to repair it.

The lack of system resources is due to the fact that too many services are enabled in the background. Some unused processes can be shut down--- virus self-loading cannot be ruled out. You can make the virtual memory a little larger and put it on a disk with more space. Make it a good habit to clean up your system junk frequently.

You first check if there is a graphics card driver, and then go to the antivirus, see if there is too much software installed on the computer, etc., and then see if the memory is enough. If that doesn't work, it is recommended to reinstall the system. Copy out the important information inside.

Hello, it is recommended to upgrade the antivirus software first to check for viruses.

Solution: 1. Observe whether the display has a black screen or a picture, but the picture is abnormal; If the screen is black, it may be that the computer is back to sleep or the respondent is dead, you can restart the computer to try; Of course, it can also be caused by a malfunction of the computer hardware, not necessarily a malfunction of the monitor.

2. If it is not a black screen, the display screen is displayed, but the displayed screen is abnormal, such as a lot of horizontal or vertical lines, or a blurred screen; This situation is mainly caused by display failure, such as screen line aging, breakage, high-voltage board failure, poor power supply, display chip failure, etc., which need to be solved by contacting the laptop's after-sales service for testing and repair.

Whether the screen is also this color before entering the system, if it is this color, it is a fault of the screen cable, generally not pressed and loose.

Elimination. First look at whether the light on the keyboard on the right side of the keyboard is on,When it is on, check whether the connection between the computer host and the display screen is plugged in tightly,If it is not a problem with the wire,It must be a problem with the graphics card in the display or host,Open the chassis and pull out the graphics card out of the gold finger with a skin or A4 paper to wipe it,If it is invalid,Send it for repair。

If the light on the keypad is not on,That's a problem in the host,Open the case first and pull out the memory module,Wipe the memory gold finger like the graphics card said above,Then install one to see if you can come。 If you can't come, try the graphics card again, it's not good, try to change the power supply, it's not okay, that's the motherboard or CPU, the CPU is unlikely, the motherboard is likely, send it for repair!

If you can't understand what I'm saying, don't try it randomly, just send it to the repair shop, and give professional things to professional people to do a good job.
