You can use KernRate and RATTv3 to trace the offending driver if you're feeling up to it :)
 
RATTv3 doesn't work on Vista and KernRate has been replaced by a built-in tool on vista. By the way i've tried both anyways. :P RATTv3 didn't work and the built-in tool didn't indicate any real problems.
 

Have you tried disabling the "Broadcam Netlink (TM) Gigabit Etherent"

I have device in my Gig laptop and it was occasionally giving me red bars, so I disabled it, and all is fine now :)
 
Yes, it is disabled. :)
 

What about the "Intel(R) WiFi Link 5100 AGN" is that disabled too. Going on your screen shot, it's not.

I would disable that mate.
 
Tried that already, it fixed nothing. :)

How about xperf?
 
That program makes my brain implode.
 
 


Can this be a problem? :)
 
Is that at idle?!
 
I think... at least as long as Xperf doesn't use to much disk activity :)

Funny - i didn't notice this in windows itself...
 
 
Info: i've fixed this.

Windows 7 took care of the 1000µs peaks and turned them into 200µs peaks, which is acceptable. The 18 000µs peaks were caused by a function of my graphic card called "Powermizer". Turning that function off (which is not easy, because well... actually you can't) fixed the problem of huge spikes. This might be of use to others experiencing the same problem. (Like the Dell Studio laptops, which could have this problem too).
