Powered gpu problem

post #1 of 2
Thread Starter 
I have the strangest problem that ive ever come across and would love to hear anybody else with this problem or maybe even a solution. i have been running a hd5750 crossfire system for over a year now, and the other day the mobo "lost" one of the gpu's.Now it wont even take a powered gpu.An old hd4350 ( unpowered) will work in it fine but as soon as i try to put a powered gpu in it , it gets just past POST then sends no signal to my monitor.I have tried all the usuall suggestions like change of drivers, reseated, replaced PSU but nothing works.The mobo seems to work fine without a powered gpu but fails after bios screen with anything powered.Im at a complete loss to why this is happening.Any suggestions would be much appreicated as i have been working on this for over 3 weeks.

GPU asking too much power of the PCI slot?
maybe the capactors on the motherboard cannot handle the requirements needed for that GPU?

Never seen this sort of problem before, I would replace the motherboard just to bypass all possible reasons for this happening.
