I have a HD7870 as the title suggests, and I am having a problem; the problem I am having is that when I run my PC out of Safe Mode, if I do anything other than Skype or FurMark, it black screens, or similar.(e.g. Blue screen[Not BSoD], Frays the screen, blanks it, etc.) If anyone else has had this problem, and knows how to fix it, it would be much appreciated. Also, it is the reference design of the card.
I also hear a sound that is sort of like a semi screeching fan or a screeching hard drive, but it's neither of those.
