PC extremely sluggish, CPU going crazy

Seem to have an issue where by my dual core CPU is going crazy for no reason and I can't work it out why.

My CPU seems to be going along at at least 60% on both cores, even when nothing is running.

Checked the task manager to see if any processes are hogging my CPU, but nothing is listed, so I downlaoded this little tool called Process Explorer from Sysinternals and it lists 40% being eaten up by Deferred Procedure Calls (DPC's).

I can't kill these things - TBH don't have a clue what they are - so what are they and why have they appeared out of nowhere? It's bugging the hell out of me.

This is Vista 64bit btw, with 4gig ram and an e2160 cpu (I think). All updates installed.

EDIT: Internet explorer seems to take up an inordinately large amount of CPU time as well for some reason.

I cant even remember to be honest. How would I find that out?

I tried doing the above anyway but it hasn't worked unfortunately.

BTW - forgot to mention that I did the DPC checker thing and it spikes frequently into the many thousands, so I think something is up along those lines.

EDIT: Yes its a Gigabyte. It's a P35C-DS3R F6.

Is there any way to run 32bit programs on 64bit Vista? I'm trying to flash my bios but it won't do anything and I can't seem to find an updating tool that's 64bit. Cheers.
