Usually when I first boot the machine, things are fine, but within 30 minutes or so it starts happening. I've done all the normal checks (spyware, AV, starting without background processes, etc).
Dell is sending a hard drive replacement but that doesn't make sense to me. It's probably just their way of getting me to reinstall windows and everything else so that the real problem goes away
This is a Dell Insprion 8600, 2GHz, 1.5 GB RAM, 60GB hard drive, integrated Broadcom 10/100 and Intel Pro/Wireless 2200BG. It is connected to a docking station most of the time.
