GPU crashing every 20 minutes or so.
I recently got a new PSU (http://www.thermaltakeusa.com/store/Product.aspx?C=1016&SC=1026&ID=1776) in order to support my GPU (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121432) because my older one couldn't handle the GPU due to a bad power rail. But now, even with this new PSU, my video card is crashing in performance mode. Is this PSU still not powerful enough? All i have are 2 fans on the chassis, in addition to a CPU fan, and a 1TB HDD. Drivers are also up to date, and I can't think of anything.
