Im helping a friend build a computer for Christmas. All parts are suppose to be compatible. When we went to boot all fans started running and it sounded like a normal computer boot but no video displayed on the monitor. I tried reseating the graphics card, swapping graphics cards, reseating and switching out the ram and no luck at all. Also his graphics card fans didnt turn on but my much less power hungry card seemed to be running fine. Not sure whats going on, Im thinking its the motherboard or psu.
