Ok so my friend bought a Geforce FX 5700LE, and he wanted me to install it becasue i knew how. Well I hooked it into the slot, and put the drivers cd in. It started up fine, and i installed the display drivers first. Everything was going good, it told me to restart the computer so I did. When the computer started back up, well...it wouldnt. It just sat at a blank screen, but I could hear that the computer was processing, so we waited for like 5 minutes. Still nothing. I decided to shut it down, take the video card out and plugi the monitor back into the mobo. It then came up with an error that said a certain file has been damanged, and it would take the windows startup cd to fix it. So we put that in, and it repaired it so windows started normally. We try to put the video card back in and it still wont even start up. Then I plugged the monitory back into the mobo, but kep the video card in the computper. Then it started up and i installed the drivers, display drivers, nvidia drivers, everything that was on the CD. so we try starting it up on the video card and it still doesnt work. What could be the problem?
