I do not know if the folowing will help or hinder,BUT,,when I replaced the video card on my rig,[A7V880,Barton 2800/5900Xt,AGP,XP PRO /S2] I did NOT remove the old drivers,Because the last time the last I did remove prior to installing a new card all hell broke out,so instead I leave the current drivers in install new card,XP of course has a righteous fit,jumps out and ky-yiees around on the floor for a while but eventually it settles down to a 800X600 screen,from 1024x768,and then I install the drivers again,after all it is still the 81.98 forceware for all nvidia cards,mind you, I do make a ghost first,after all paranoia runs deep with windoze.
Also ,??have you tried your card in another rig ??,,,,,,,,,,,you might want to check in other posts to see if any one has had similar probs with your combo of mobo/pwr supply????/vid card.
In any event take your time and be carefull.
EDIT,EDIT,,,If your monitor is blinking it is not,,REPEAT NOT ,,getting a signal from the vid card. Dokk.
Yes, I tried both outputs. I spoke with tech support at eVGA, Mwave, and Dell. Dell even walked me through the install to make sure I was doing it right. I was. All three tech supports said it's probably just a bad card.
Yep, mine was definitely a bad card. I don't see any other explanation. My new card, an eVGA 7900 GTX, arrived today. It installed flawlessly. I did absolutely nothing different. I only had to move my sound card to another slot. Otherwise the big cooler on the GTX would have been just under it. I thought more breathing room was better.
So far, the only games I have tried with the new card are FEAR and COD2. My performance in those two games has literally more than doubled. I'm very happy with this card so far.
