Hi guys, if some kick ass person could help me out with this I would really appreciate it. I downloaded Process Explorer, which has told me the reason my CPU usage was 5-70% while System Idle was 99% was "Hardware Interrupt". Now while I've read up on a basic definition of what Hardware Interrupt is what I really want to know is what exactly is causing such a high CPU usage, and how do I fix it. It's really slowing down my computer on off days and making start up super slow. Any ideas?
