TechGAF I come before you with a problem.
Graphics card: Radeon R9 200 series (Direct CUII) - I don't remember the precise model number, sorry. It's got 2 x 6pin power connectors though.
I've been getting these white screen graphics crashes where my screen would just go completely white and then freeze up (audio hangs etc) for a few days now, I just dismissed it (they disappeared on a forced reboot), but the latest one apparently took down my graphics card's display output. I've been trying to fix this for about three-four hours tonight and have gotten far in terms of narrowing down on the actual problem, but about zero in terms of fixing the fucking thing.
After a lot of fucking around I managed to get the PC working again by unplugging the card and using the mobo to force it to boot to integrated graphics, checking if that works, then plugging the card back in but using the mobo graphics from BIOS.
Poking around after that, it's apparent that the graphics card is a) recognised and b) working as far as the system can tell, except that it won't actually display anything when I switch everything back around. Fans spin, LEDs light up (so it's drawing sufficient power), but if I head back into the Bios to switch it back to PEG or whatever it just wont' work. It won't output HDMI or DV-I, at least to my knowledge.
I ripped out all installed graphics drivers from the rig and then used radeon utility to clean it out and then reinstall the latest stable drivers, nada.
i'm tearing my hair out here. I was going to get some fucking study done tonight but who knows if that's going to happen even tomorrow... if anybody has any clues please let me know. As far as I know i didn't make any changes in BIOS or otherwise, didn't install anything new, nothing, it just fucking blew itself up.
Things I'll try tomorrow if I get home on time:
reset bios to default
update bios
reseat the video card more?
I'm just glad I haven't lost any data.
By the way the box this is in is tiny, so there's no other PCI-e slots I can jam this sucker into. It's difficult enough unseating it and reseating it as it is.
Card (and the PC as a whole) is about 2-3 years old at this point
