Why can't the computer start normally after the driver is installed in the graphics card?

1. When installing the machine, the technician executed the file agp 168e.exe when installing the driver. So there has been no problem in the use process, but I didn't know it when I reinstalled the system. I directly upgraded and installed the graphics card driver, but didn't run this program, which caused the system to be extremely unstable and the video files often crashed. Because the current CD-ROM drive is quite intelligent, I suggest you run and install the driver directly.

2. In addition to the driver, sometimes the computer can't start because the resolution of the monitor is too high. Because the monitor or graphics card doesn't support high resolution, when we can't enter the system or screen, we can switch the startup mode to safe mode, then enter the display settings under Windows, and then press the "OK" button after completion, and then restart to solve the fault.

3. In addition, there is another case where the driver of the graphics card is loaded due to the poor compatibility between the graphics card and the motherboard, and the driver is automatically lost after running for a period of time. In this case, we generally think that the poor quality of the graphics card or the incompatibility between the graphics card and the motherboard leads to the high temperature of the graphics card, which leads to the unstable operation or crash of the system. At this time, you can only replace the graphics card.
