I'm asking on behalf of a friend who I helped to build a PC for today. We built it and started it up with no problem, the Motherboard light signalled it was fine and being powered, fans spun, CPU worked etc. But when we tried his GPU (XFX R7 260X) it would not start at all. Unfortunately his motherboard, an Asus M5A97 R 2.0 has no onboard video output so we couldn't have a look at the BIOS or anything.
We decided to try it in another friend's PC who's running a Z87 motherboard with an i5 and it worked fine. So what could the problem be? I doubt it's the motherboard's PCI-E lanes as the card is failing to start at all, we believe it may be the power supply and I'm planning on testing my PSU in his system tomorrow to see if that may be it. Might there be anything else that could possibly be the problem?
