I am having issues with a new graphics card I have purchased, an evga GeForce gtx 750 ti. My old card was a gigabytr amd radeon 7700 hd. The problem is is that when I put the gpu in, my PC gets stuck on the bios screen and I can't press anything or do anything. Eventually the monitor will go to black and a line will be blinking in the top left corner. I am using windows 7 64 bit and a gigabyte b75m-d3v mobo. Any ideas?
