Good day, I have an Asus HD7750 v2 that is not working. It started when I flashed the latest version from here. I had it flashed using ATIFlash on Windows. The card now is undetected by both Windows Operating system and ATIFlash. The fan is still running however no display. I tried different PCI-e slots and even used a GPU riser but still not detected. I found out that the bios chip of my card is a PM25LD010 (see attachment for pin diagram) . I am just wondering which pin should I connect. Is it 1+8 or 4+5.
