OK, Henrik old buddy, you explain this one to me?
So I enable HT with a repair of XP, I get the same CPU usage you had, removeing the two hotfixes referenced in your thread had no effect, disabled one of the USB controlers, all was instantly well on that front.
So I start up CPU burn after disabling ACPI and starting your temp monitor, I saw a smilier trend in temps with one instance, it only hit 81 in the normal five minute span, but it was climbing. At that time I said oh well and started up another instance of CPU Burn, and what do I see? The temps go DOWN! I'm sitting here looking at a 69 degree reading where it settled from it's 81 and climbing with a single instance running. I am so stumped by this one I don't know what to think.
Thoughts? And if there's anything else you'd like me to do on this install speak up, I want to install fresh with HT enabled ASAP.
This is so strange..
