Long beep during startup to determine graphics card failure
[
Views: 427 After the computer starts, it emits one long and two short, a total of 3 beeps, and the display is black
The display is black when it is turned on, and the speaker in the main box emits one long, two short or three short beeps, indicating that there is a problem with the graphics card. At this time, you need to open the case, check whether the graphics card is correctly and tightly inserted into the graphics card slot of the motherboard, and whether there are foreign objects in the graphics card slot. Meanwhile, if the graphics card is used for a long time, check whether the "connecting finger" of the graphics card is oxidized or dirty, and wipe the "connecting finger" clean with a clean high-grade eraser. If the above method still does not solve the problem, you can change to another graphics card for testing.
