Hi, I've recently bought a 660ti that didn't work properly when I first got it. i was helped with driver issues and BSoD's stating "IrQ is less than...". Now I'm getting BSoD's stating Memory dumps. I'm wondering if this is a truly defective card? My ran memory test through windows and came up with no errors. I have a Sabertooth Z77 MOBO, 8 gigs of Ram and a 750W Power Supply.

All of these problems started when I replaced my old card due to a buzzing sound in the fan with this GPU. I'm wondering if there is some way to change the power of the card? I know just a little (nothing technical) about computers, but this has me stumped.
TIA
