I recently posted a while back an issue I was having getting my Geforce FX series card to work with my system. The guys here at techspot went round and round with me offering useful advice and really helped alot. However, it turns out the problem was much, much simpler than anyone originally thought. Hopefully this will save all of you some time and headaches. Before you chalk up your problem to a memory conflict, bad ram, bad card, hot card, mobo issue, system failure....anything.... before you tech a problem like that, you need to download and try older series drivers for your card. I repeat, the newest nVidia drivers ARE PROBABLY THE CULPRIT!!! I found a site, www.guru3d.com that has all the copies of nVidia Forceware and Detonator drivers. For the FX series of GeForce cards, they recommend not using any Forceware drivers higher than version 66.93. That's what I downloaded and installed, and my card has been running beautifully. I've had excellent benchmarks for its capabilities, great graphics and performance, and zero conflicts or crashes with my system. They also have a stickied thread in their forums that tells you each line of nVidia cards and the recommended versions of the drivers that are known to work well with them. So a word to the wise, before you trash your card or put it up on eBay, look up the known series of drivers and try them out, if none of those versions of the drivers work (there's several, try them all) then you can go forward with the teching. Good luck!!! ps. Thanks to Howard_Hopkins for all the great ideas. You were an invaluable resource in getting this issue resolved.
