So for 4-5 weeks I'd been able to play BF3 no issues.
Got latest beta drivers couple days ago, installed, started crashing every 5 minutes.
Did some Googling, found out about the new bios update and installed it yesterday (was first time, but i followed directions to the letter and found it to be quite simple)
Reset my computer, managed to get in 20 or so minutes of BF3, then BSOD. (temps peaking at ~60-65C)
On windows startup (logo appears, no further) I'd BSOD. So i uninstalled the drivers and the GPU, let windows "find" them and managed to get windows started, but i had strange blue lines across my screen, and if i'd install drivers (from original CD, or from NVIDIA) I'd return back to BSOD on startup.
I'm thinking it's a faulty card, but it was working for roughly 2 months before this happened, and haven't made any hardware changes since. (I've since removed the 560ti and replaced it with an older 8800gts.)
