So I found this option in my bios called HPET under power management. It has an option to set it to 32-bit or 64-bit. I'm not a 100 percent sure as to what it does, but from what I could find, it relates to video. I'm running Vista 64-bit, so I figured I'd set it to 64-bit (and apparently the setting is only for Vista). Although, just because my windows is 64-bit, sometimes setting things to 64-bit isn't a good idea.

Anyone know if I should put it on 32-bit instead of 64-bit (I manually set it to 64-bit first day)? I've been having issues with dx10 games since I put this rig together, my video drivers crash after about 1-4 hours of play on dx10 games (yes my drivers are updated, and so are my games). It's some nxblahblah.something error and my video drivers try to recover from it after a while, I've heard of quick fixes, but nothing to do with HPET. It's not an uncommon problem apparently.

Any help would be appreciated. Thanks in advance.

Try it both ways. See which works better. Have you upgraded to Vista SP1? If I recall correctly, that was released not but a month or two ago...

DX10 has many performance issues across the board. Coupling that with a new OS, I wouldn't be surprised to encounter a problem here or there.

A crash screen that displays an NVdspwhatever error is completely a driver issue. Try rendering the game in DX9.0c and see if the persists. I know that the most recent game I've been playing, Hellgate:London, has issues in DX10 mode.
