For graphics card cracking, overclocking or silent modification, flashing the BIOS is a once-and-for-all method, but once the flash fails, the computer cannot start (black screen).
You need to understand the cause in order to solve it in a targeted manner. The problem of light failure is generally caused by the following situations:(recommended learning:web front-end video tutorial)
1. The BIOS is flashed incorrectly or damaged, or the BIOS information is incorrect due to customer overclocking.
2. The power supply of the graphics card is abnormal. The specific cause is unknown. Many of them have a lot to do with the manufacturer's design and materials. We once encountered a customer who had more than 30 bad graphics cards of the same model, all of which were damaged in the voltage part
3. The oscillation circuit of the core reference frequency is damaged, causing the graphics card to be unable to detect
4. Core damage. This fault is generally caused by excessive temperature of the power supply part and graphics card. It may also be caused by improper fan installation and user overclocking. This kind of fault is relatively easy to diagnose and repair quickly
5. There is also a situation where the display light is between green and yellow, which is caused by a problem with one of the line and field signals
6. The last one still depends on the monitor light. The monitor light is green, but the picture cannot be seen, and the system can be entered by listening to the sound and it does not crash. The graphics card has been found by the system because the three primary color signals of red, green and blue are not caused. This fault is difficult to repair on some graphics cards. It is caused by the leakage of a very hidden feedback signal. (In addition, the source of the dark screen fault is also a problem with this signal.)
