Description of Original Problem: when I use my pc, GPU clock randomly set to 2670 Mhz, causing crash of games and applications. when I put it at the right clock and apply it, after a bit it returns at 2670Mhz by itself. i can't use my pc like that. (i tried changing it from adrenalin software, as well as msi afterburner.)
