Re: High CPU usage due to Hardware Interrupts

Dear Bert

I really appreciate you helping me patiently and thank you for that. I tried
to unplug all my USB devices, but that does not make any difference in the
CPU usage. I looked up the Properties of this Hardware Interrupt process in
the Process Explorer. Every item in the Property dialogue box, under every
Tab is either empty or says n/a. I tried to Suspend or Kill the process, but
it gives me an Error saying the parameter was incorrect.

Is there anything I could do or see in the Device Manager. Or is there any
way I can find the address of this Interrupt and then do something about it?

If nothing works, is the only way to clean the disk and reload everything (I
recently had to do that, and don't really want to do that again), or is there
anyway that I can only uninstall all hardware and install, without having to
touch the windows.

Any suggestions welcome.

Thanks again
