A few months ago I bought a BFG GTX 260 Maxcore 55. I installed it and everything seemed ok, I ran crysis for a bit and it was fine, and it suddenly blue screened on me, and everytime i started it up once getting to the desktop.
Now, I did install it with a 300Watt power supply in my computer at the time, so i purchased a Corsair 550watt one and tried again, the same thing happened. I presumed the card was faulty and sent it back to BFG.
Today i received the replacement card, installed it, exactly the same thing happened again.
I could really do with some help, my PC specs are as follows:
Intel core 2 duo E8200 2.66GHZ
550 Power supply
Windows Vista 32bit
