I got it working by flashing the bios. Thank you all for your help.

I am experiencing the same problem. However I have not tried replacing the motherboard. I have done everything else. My motherboard is an MSI p6N Diamond with the nvidia 680i sli chipset. I have 2 Geforce 7800 GTX and I have tried both Windows XP and Vista with the latest forceware and nforce drivers and I am still getting the same choppyness when I move my character in a game. I checked the BIOS on the motherboard but they seem to be the most current. Should I try anything else?

Have you gone to the motherboard support pages to see if a different version bios is there? Also, try their faq pages to see if other users experience the same problem. Check the game site faq's too. Is it confined to one type of game like 3-d games or is it on any games?

I have updated to the latest motherboard BIOS. Updated the graphics and motherboard and sound drivers. The same thing seems to happen with all 3D games. There is 1 thing I havent tried which is upgrading from the stock cooler to a better one. I know the pentium d's ran pretty hot and it might be getting too hot. Other then that the only thing I can blame is the motherboard which I hope isnt the case. Has anyone had this happen to them?

**RANT!**
Isnt this a bit far fetched? Telling someone it may be hardware related when it fact it could just be a few GFX driver settings?

As I understand you can force games to run in DX9 mode. Also have you tried setting "Vertical sync" to "off" in the Nvidia control panel?

What about setting the "Maximum Pre-Rendered Frames" to "1" instead of "3"?
Play around in your GFX cards control panel before doing such drastic measures. This whole "Update to the latest driver" talk in silly. Latest drivers incorporate updates\fixes to the latest games. WoW is pretty old game, yet no one has suggested trying an older version of a driver. Just because it's newer doesnt mean it's better!

**Rant over**

I have tried what you said and forced hte Vertical sync to off and set the Maximum Pre-Rendered Frames to 1 and have changed drivers.. same result.

I have noticed that the CPU usage spike up to 100% every time there is a slow down. This could be motherboard related or hard drive related (seek time etc). I have already tried a different hard drive and installed windows with the same result. They were both using the SATA bus of the motherboard. Just to try it out I will install windows on a IDE hard drive to see if I have similar results.
