gtx 460 horizontal lines
hi folks
I recently upgraded my old 9600 GT for something with a little more oomph - a GTX460. my card has been performing swimmingly until recently - ive noticed strange, wavy horizontal lines/flickering on screen in dark areas - particularly in games. this is usually accompanied by whining/buzzing sounds from the card itself. needless to say i'm concerned. I've checked and rechecked the drivers, booted into memtest for a full ram check and contacted the vendor (palit) without any luck. Its not a heat problem as far as i can tell, under stress the card hits about 61C maximum.
any ideas what could be causing this??
