I have given him back to card and asked my parents if they can get me a gpu. I just bought on what a EVGA GTX 760 2GB FTW for $60.00. It will do fine for me since I don't play crazy games. I believe he did some crazy overclock which lead to the problems I was having.tennis2 is right, you should RMA your card. Undervolting will not help. Also you say that your friend gave it to you, did he do some crazy OC on that thing which damaged the card. Just a general advice never attempt OC unless you have something stable like watercooling. Upgrade your motherboard BIOS also to the latest version.
