GeForce GTX 460 Blue Screening

Hey guys, a friend of mine recently gave me his GTX 460. I had it for a while with no problems, then suddenly it started blue screening every now and then. I updated the drivers and it began to crash very frequently, like 5 minutes upon startup. I flashed/updated my BIOS and the crashing seemed to stop for a while, but I came home to an idle computer to see that it had blue screened, unfortunately. I used whocrashed and this is what it gave me. Thanks in advance!
