The graphics card is damaged, how to repair it?

For ordinary computer users, it is the best way to send the damaged graphics card directly to the after-sales or repair shop, and it is generally worse to toss it yourself.

For professional users, I don't think I will ask questions. Generally, the maintenance of the graphics card is to check whether the PCIe data line and various power supplies of the graphics card are normal, such as whether the video memory, core and driving power supply are working normally, and judge whether it is a power problem, a video memory problem or a core problem. If it is the core problem, there is basically nothing to fix. If it is a power problem, it depends on whether it is a power chip problem, PCB disconnection problem or MOS tube burning and breakdown, and make corresponding treatment.
