Re: 820-2915 no video
thanks for replying. I did GPU bypass just to see if the problem was the GPU, but since didn't work I flashed the original bios, and soldered the resistors back, so everything is back to normal but still doesn't work. at this point dont know what to do.

Re: 820-2915 no video
yes, no beep without ram at all, no usb activity.
to bypass the gpu someone gave a bios with the gpu disabled and I removed 2 resistors R8904/11.
I checked that area and looks good to me. what exactly should I look for in order to determine that everything is good, since I'm a newbie.Leave a comment:
