had a r9 290 go bad on me while i was turning on my computer and when it came back on it wouldnt even show the bios until i cleared the jumper and removed the battery, so i switched back to my old 280x which is confirmed working from a different computer and now my computer gets stuck on checking nvram and freezes. Tried to reflash bios but the asus ez flash 2 utility in bios keeps freezing on loading as well, so im not sure if the nvram hang up is because of bios corruption or not. so I thought id ask on here and see what people can offer in terms of help.
