I just got a new graphics card (ge force gt 640) to temporarily replace my main graphics card (ge force gtx 660) is sent in to evga for replacement. I was putting in the new one and was having strange errors. Everything on screen was red then just black. Then I reset it and the Motherbord fan would not turn on and red leds would be on and after it being on for 5-10 mins it would beep then stop. I have no idea whats going on and I can get pictures if it helps thank you.
