Solution to Color Spots on Laptop LCD Screen
Driving problems
This is also an important reason for the splash screen. It usually occurs after the replacement of the video card driver version, or it may be caused by the corruption of the driver file. The solution is simple. Reinstall the driver that has passed Microsoft WHQL certification, and the version does not need to be new. The first thing you need to check when you paint the screen is the video card driver, which conforms to the principle of “soft first, hard second”.

Temperature problems
This problem is not only because the temperature of the graphics card, processor, memory, and even the chipset of the motherboard is too high, which can also cause a splash screen.
This usually happens in summer. However, in winter, if the radiator falls off and the fan stops running, the temperature of the hard disk may also be too high indoors, which cannot be ignored. It is recommended to open the chassis to check the installation of each radiator, and try to open the chassis to run games, Check to see if the screen will flash again. If the fault disappears or the time is delayed, it can be basically determined that the problem is temperature.
Power supply problems
Solution to Color Spots on Laptop LCD Screen
The AGP/PCI-E 16X power supply includes the power supply and the motherboard. If the graphics card does not get sufficient and pure current, the screen may also be distorted. The solution is to disconnect the optical drive, independent sound card and other non essential hardware, reduce the load of the whole machine, and then try again.
4、 There are many reasons for the video card problem. The BIOS of the graphics card may be defective. This can be solved by refreshing the VGA BIOS; It may also be that the video memory is damaged. This is a common situation.
There is no personal solution. In addition, if the screen is damaged by the core, the video card can only be scrapped; It may be that the golden finger has oxidized or there is too much dust, which is the luckiest. Just clean it up. The oxidized part can be wiped with rubber, and then washed with anhydrous alcohol, and the fault disappears;
Another problem that cannot be ignored is the capacitance on the video card. Many video card screens are spent because of the capacitance, and some manufacturers even throw them away (the famous king of screens).
In recent years, emerging video card manufacturers have also adopted some capacitors that are not often sensitive to temperature because of cost saving. They will spend the screen when the temperature drops in winter. Theoretically, the fault is eliminated after replacing the capacitance, However, it is recommended to contact the dealer for replacement or return to the factory for repair.

Memory module problem
If the screen is not caused by the above reasons, you can consider whether it is caused by the memory module damage. You can wipe the dust off the memory module, and then turn on the computer to check whether the screen problem is solved. If not, you need to replace the memory module.
The above is the solution to the color spots on the computer screen. I hope it can help you.
