660Ti Goes Black with Fan RPM Suddenly Maxing Out

Hey guys.

This is making me want to suicide, please help.

My display suddenly goes off (monitor shows no signal) and the EVGA GeForce GTX 660 Ti's fan's RPM suddenly revvs up so much that it literally sounds like a hair dryer. After about 5-10secs, the PC reboots itself, coming back to the desktop with a BSOD notice saying PC shut down unexpectedly etc etc. And sometimes the cycle continues without the fan revving up.

This is the BSOD error:

Possible reasons according my understandings:

1). High temperatures? I am quite sure it has nothing to do with the temperatures as the CPUID HW monitor shows 'maximum' temps of about 75*C when playing games. Idles stays about 50*C. My computer casing is a SilverStone PS06B-W. Max GPU temp for this model according to geforce.com is 97*C.

2). Insufficient power? My Platinum-rated PSU (550W) should be able to support all these equipment. But your opinions are very much welcomed.

3). Bad drivers? My computer is after a clean reinstall (new windows, new everything). These symptoms were showing even before the clean reinstall. I use the latest GeForce drivers from the Nvidia website (v310.90). But occasionally, I do get a "Display driver has stopped responding and has recovered" error.

4). Bad hardware? This is my second 660Ti. After a few days these symptoms were showing, my previous card showed signs of hardware-level damage (there were red dots/lines all over the display even before the OS bootup). My current card is an RMAed one of that. I doub't I can score two bad cards in a row, but still, opinions welcome.
