Dave, I wish it was so simple. I updated every driver I could find,
including the bios. I'm still having this problem. Even in safe mode
with only two services (DCOM and RPC) the hardware interrupts was eating
up 20 - 40% of my processor. The only reason I don't think it is
hardware related is because when I don't open a program the cpu usage
gadet sits around 10% as soon as I open any application it jumps up to
50% and never goes below that. The weirdest thing is that in the task
manager you can't even see the cpu usage. You have to use sysinternals
process explorer. That tells you that it is a hardware interrupt.
It seems I need to reinstall the OS. Well, it won't be Vista, if I have
to go down that route. It will either be XP SP2 or Unbuntu. The thing is
that I like Vista other than it is broken. On my dual core desktop Vista
Home Basic is faster then XP. It is great. But on this laptop (which
came with Vista, ironically) it doesn't work. Granted I did reinstall
Vista once already but the problem was a bad stick of ram. So I really
didn't need to. I don't want to make that mistake again but I don't know
what to do.
