Re: GTX280 Starts but Hard Locks During Games!
I keep thinking maybe it's your PS or how you connected the power to the card. I ended up buying a 260GTX (216core) card because I didn't want to buy a new PSU.
Are you sure the power connectors going from the PSU to the Video card are from different rails? IIRC BFG says their 280GTX requires a total of 42 amps over 2x12v connectors so if you are just splitting one from a single rail there is a good chance there just isn't enough power when it starts to really work in the games. My PS specs says I can only do 19A over a single rail so I max out a 38A over 2x12v rails, so the 280GTX was out unless I was willing to buy a new PSU.
