I have had an issue with installing my new graphics card, a NVIDIA GTX 760. I've plugged it into the top PCI-E port on the mobo, and every time my machine tries to boot up outside of safe mode, the screen flashes and freezes up with unintelligible black blocks. I've eliminated any issues with my PSU, the board's PCI-E port itself, and a bad HDMI cable (I've tested the card on two different monitors and cables with the same result). It has been recommended to me to update my mobo's BIOS and reset everything to default, but I wanted to make absolutely certain I had to do that. Any help in this matter is greatly appreciated.
