I recently installed a gtx570, everything has been swell...BUUUUT occasionally, when i play a game, and exit out(or tab out), the home screen resolution goes to 800x600 all by itself for some reason....it's happened during witcher, sc2, WoW, and Microsoft flight sim X....it should be noted, that it happens every time i play a NEW game, like, the 1st time i launched WoW, then tabbed out, it happened, the 1st time i played SC2, same thing...it only happens when a game is played for the very 1st time...does not happen again for some reason.
also, another odd question, every time i play the witcher 1...when i close out, windows media center automatically launches.
core i7 920 2.66ghz
dell 20" monitor, 1600x900max res.
I have the same problem now but it happens with me every single minute , without even opening 1 game or anything please someone help me !!
