Hi, recently a video card of mine started to get graphical errors so I figured the card was going bad and bought a new one. Untill the new one arrived I put in my old geforce 2 pro, but now when i tried to install my new video card it wont work at all. I reseated the card multiple times but to no success, the monitor still remains powered down when I turn on my computer. I've even tried putting my old 9700 pro that was going bad back into the computer and the monitor wont power up for it either. I've disconnected everything but my hard drive and motherboard from the power supply in hopes that maybe I just needed more juice but that doesnt work either. Please help if you can, having 1 card work but others not is frustrating and I can't figure out what is wrong.
