I recently upgraded my graphics card from a gtx 275 to a gigabyte gtx 560 sc. after a few days the screen started to black out and says it has recovered from a driver crash. From there i did clean installs of older drivers to see if it would fix that. using 275.33 fixed that for the most part but then in game (skyrim+wow) the card would auto downclock to 405MHz and wont go back up to default or factory stock speed until system restart. also sometimes it would studder then reset the clock speed i set using afterburner(822) back to 900. running benchmarks doesn't do any of this and it doesn't seem to be a temperature issue. ive also updated my bios, swap out to my gtx 275 using both old and new driver and different slots. old card works fine in both slots and drivers. and used memtest on all my ram sticks and removed any that were questionable. wow+skyrim=crash but benchmark+swtor doesnt.
