W7 Experience Index Freezing

[Theblackoutow]

Title kind of explains it all, when I run the experience index it freezes my computer. Any thoughts?
Update: It specifically freezes when it gets to "Tuning Windows Media Decoding"

Sounds like a Windows Codec problem

Have you installed any codec packages? If so, uninstall and check

Also, posting a hijackthis log might help us out

I just did ANOTHER fresh install of Windows 7 because it wouldn't let me log into my account, and none my restores would work... I'll see if it works now straight after a straight install.

Still doing it...
