That's normal. If you wish to understand IRQs, you have some reading to do. Interrupt requests are a fundamental part of how your system shares cpu resources. In the old days, you had to manage IRQ channels manually!

I just reinstalled windows again, so far so good. All updates are applied. I selected "Apply only important updates" and am going to be more cautious of the software i install. Its nice to have 20% more CPU, especially for BF3. thanks anyways guys.
