I built my first PC today and everything is perfect except for my graphics card. I have a 6950 OC'ed edition by Sapphire and I installed the correct drivers, went into the BIOS ad used PCIE as the first graphics booter, the light is on and then fans are as loud as %*@! however I can plug my VGA to DVI in but no signal is received from my monitor. Any help is appreciated, very very frustrated.
