I have been trying to help my friend who is having a problem but I have tried everything I can think of.
OK, he recently bought a motherboard to replace his old one that was having problems. I set it up and installed everything for him and it was working fine.
Two days ago he shut down his PC as normal but when he turned it on again later there was no video. I tested his onboard graphics and it worked.
I thought it must be the card then - but I tried his card in my PC and it works fine. I then thought maybe it's a dodgy PCIe slot - but I tested my card in his and it worked fine also.
I have tried:
Resetting the BIOS.
Taking the PC apart and putting it back together.
Testing card in different PC - works fine
Testing different card in this PC - works fine
Putting my PSU in his PC in case it was his PSU and still the same problem.

If anybody has any ideas on how to fix this I would appreciate it. Clearly both boards and both cards DO work.
