I am having an annoying problem of high cpu usage on Windows 7. I am not sure when did this problem started but i noticed it yesterday and i have been trying to solve it myself ever since without any luck.
Ok so here is the problem:
I have Intel Core i7 920 CPU and 1 of the processor's core is always at 100% load. Its always the same core, i have tried restarting my pc into safe mode and the core was still at 100%. Looking at the resource monitor does'nt provide much information as the process which is causing the load is "Deffered Procedure Calls and interrupt service routines", here have a look:

Doing search yields that this is a driver related problem so i have tried un-plugging all peripherals which does'nt help. Finally i downloaded and run xperf and looking at the report from my limited knowledge i concluded that its intelppm.sys which is causing the problem. This is a windows default driver for intel speed/power management. I have tried everything to delete/rename it (tried VMware/safemode) but i can't seem to, i have also tried disabling intel speedstep from BIOS which did'nt help.
I am completely lost now and hence i am posting my xperf results here so maybe someone more knowledgeable can have a look and provide some insight whats wrong.
EDIT: Link deleted as the problem is solved now.
