I just finished my build. However when I plug my vga cable on my monitor my monitor stays blank and the power light stays yellow. But when I plug my vga cable on the onboard graphics card with my motherboard, it shows a display. The 5850 doesnt even show up in Device Manager. Thinking it was my motherboard I tried it on a brand new MSI, however all I get is 1 long, and 2 short beeps which is an error for the video card. Did i get a faulty gpu?
P.S. My motherboard is a Biostar TA880GB+ and my PSU is a Thermaltake tr2 600 watts
