Just a few things out of the way
Graphical intensity of the game is irrelvant. It happens to World of Warcraft, it happens to Team Fortress 2, it happens to Portal 2, Magicka. Windowed mode does not alter the problem at all. Runnig in window mode and adjusting video settings do not help. It also will occasionally happen while watching Hulu but this is rare. It will happen when using Adobe Premiere CS5 on occassion (probably two or three times every hour).
When runnign through taskmanager I see nothing out of the ordinary taking up CPU. The only noteworthy thing I spot is that when teh spike occurs is that the game itself suddenly increase it's cpu use by about 50-75% (i.e. it's running at 25% and then suddenly jumps to 40% or therabouts) - surpassing the CPU listing for System Idle Process.
Edit: Forgot to mention - I have run OneLiveCare and Norton security - both of wihch have turned up nothing in virus or malware.
Edit 2: Forgot to also mention - I've tried updating drivers, divx, checked windows update, rolled back drivers, uninstalled and reinstalled drivers. All of which have had no affect.
I've attached a hijack this report.
Any help is appreciated. I can't play games on tihs for the time being while the system is in this shape.
