Im currently running the system in my sig, ive had the 5770s for about 2 months. about 1 month ago i started getting a driver error on startup. when i get to desktop my screen freezes and little fuzzy blue squares pop up all over the screen. it then goes blank and comes back up normally with the error message ati display driver stopped responding and has recovered. after this i have no issues at all for the rest of the time that the pc is on. however in the last few days its started happening more than once and increasingly during video playback in media player. i read that it could be to do with motherboard voltages and as my cpu was overclocked i reset it to stock setting everything to auto on the motherboard bios. this hasn't made any difference. ive also tried each card individually and it still happens. im out of ideas so any suggestions would be appreciated.
