I am really loosing the plot here - just kitting out my new ASUS A7V8X-X based system (has AMD XP3000, nvidia GeForce FX5200, 1GB ram, coolmaster fan fitted, decent 400W PSU) and it's been rather on the unstable side and Windoze/MS think it's a driver... So I took the Nvidia link for driver update - downloaded - installed, now when I even just try to check driver version it gets "catastrophic error"! I can get screen shots if people need them - but basically it is not working at all, so far as I can see. I'm new to nvidia and this is not working out too well so far - especially if that is where my system's instability lies. Any help/pointers much appreciated... I am calling it a day for tonight though I think!
