Just wanted to share a frustration...
My 3 year old dell laptop started getting slow. really effing slow. I was even getting glitches in music playback. not good when your demo'ing products and using it as a music source!
Looked at the task manager, 40% - 60% idling... but the processes didn't add up to that.
Annoying.
Got a program for free called process hacker.
Turns out, there was a significant amount of hardware interrupts going on in the system. something was causing a TON of interrupts.
An afternoon of googling found this link:
http://forum.sysinternals.com/topic965.html
Turns out, after a number of hibernates etc, XP thinks there's something wrong with the hard disk controller, and switches from DMA mode to PIO mode.
Sounds like it's basically bitbanging the hard-drive, rather than doing clean bulk DMA transfers.
Anyway, I went to device manager, removed the IDE driver and restarted twice.
Seriously. My machine hasn't been this slick/fast in AGES.
Just wanted to share my experience, and hopefully stop someone from throwing their PC out the window! ;D
