hie guys, i'm running vista ultimate and my rig is as what's posted on the sig.

i'm having a prob with it. Every once in a while (ie 10 mins, sometimes 30 mins) my hard disk activity jumps to an insane amount to the point everything slows down. Movie becomes still frames pictures.. This happens when i have new files on the computer (ie download stuff from torrents). Is this normal or is it because some program is running? checked the performance monitor and it shows my harddisk activity at 100% and it's usually one file that's being access the most. KAV does not show any antivirus scan running and there's no virus detected on the pc.

Please help me as i'm pretty worried about my harddisk lifespan due to the excessive harddisk activity. and it's pretty annoying when things slows to a stop while doing work.

it's not the torrent program that's causing the excessive harddisk access..
i've check resource monitor and apparently it's svchost that's accessing my harddisk. It's reading files randomly and causing the hangups.
