Recently got a used evga gtx 650 ti 1Gb from eBay, had it work on and off for a while with random issyes but they've gotten worse recently and I was only able to get drivers to work for minutes at a time. As a last resort I tried to flash a new bios to see if that would fix the problem, but on reboot there was huge artifacting lines across the screen and windows did boot but was unusable. Looking to possibly get the original bios to flash in an attempt to fix before I finally give up on this card, thanks in advance.

Hey thanks man, one of those fixed the artifacting from the flashed bios, and I would try the baking but the thing is that when I install the driver's then sometimes it goes into a boot loop, sometimes it comes on but artifacted and with the fan at full power, and once in a while it works perfectly without artifacting or anything though this generally decides to crash and fail at some point. So I might give it a go but seems a general issue with drivers. Thanks for the help though :D

Hey okay, might take a look into cooking it, thanks
