So my HD died, and I just got my new one. I plug everything back into my comp, I turn on my monitors, and when I turn the comp on nothing shows up on the monitors. The computer runs, and Im pretty sure my vid card works because a red light turns on and off, but nothing on the monitor. I cant figure out whats wrong. Before I had to use a DVI to VGA because my comp wouldnt work with DVI, so I thought it might have reversed and I tried DVI but still nothing. My vid card is ATI HD 2900XT. I dont think its my PSU cause its 850W but this is it, Antec Quattro 850 PSU
. Thanks in advance to whoever helps me out.
