I recently decided to upgrade my processor, and bought a suitable motherboard with it. So here's the thing, I'm currently holding two graphics cards (old: Radeon HD 5450, new: GeForce GTX 295) and two motherboards (old: Foxconn 2AA9 I think, new: Asus F1A75-V pro). I'm using a single stick of memory.

The issue is with the new graphics card and the new motherboard together. Insert either graphics card into the old Foxconn motherboard and they all work like a charm, but inserting the new graphics card into the new motherboard gives me no video output whatsoever. The old graphics card on the new motherboard works, though.

                       |  HD5450  |  GTX 295 
---------------------------------------------
Foxconn 2AA9 (AM3)     |  works   |  works
Asus F1A75 V-pro (FM1) |  works   |  fail

I also tried using the on-board graphics card on the new motherboard and got no signal from there either. When testing, I'm using the same hard drive, the same stick of memory and the same power source.

Any suggestions will be greatly appreciated.

" I also tried using the on-board graphics card on the new motherboard and got no signal from there either" could the motherboard itself be dead? any error lights or lack thereof? –  Journeyman Geek Apr 15 '13 at 7:29
    
"could the motherboard itself be dead?" the new motherboard works just fine with the older graphics card, so it oughta be fine –  Scrawny Apr 15 '13 at 8:58

Your PSU seems to work and from your OP we know that it has enough juice to feed the power hungry GTX295 (Power hungry source: geforce.com/hardware/desktop-gpus/geforce-gtx-295/… ). However could it be that the power draw of the new mother mother and the new graphics card is more than the PSU can deliver? –  Hennes Apr 15 '13 at 10:10
    
@Hennes Thats my thought as well. Scrawny, what PSU are you using (Brand, model, wattage please) –  AthomSfere Apr 15 '13 at 10:33
