I've been trying to figure our what is causing an HP Vista laptop (dual core
AMD) to hang during operation. Sometimes it will work for hours, sometimes
barely minutes. The hangs usually shows when you try to do something, and the
cursor will show the "busy" rolling circle. It seems like the harddisc will
initially be cycleing continuously (LED flashing) for a while, then finally it
will just occasionally flash. The mouse still moves, but you cannot start or
close windows. When I've managed to have the task manager running when it hangs,
I've seen nothing unusual there, but that eventually hangs also. Tasks that
won't respond will in cases show as "not responding", but trying to close them
from the task manager doesn't work. The system does not recover. I eventually
have to power it down, and then turn it on and run the windows disk check before
I try anything further. Speedfan shows to intense processing when the hang
occures.

I've run Memtest86+ and Seagate floppy based disk test without errors. The full
scan of the 250GB drive took about 2 full days to complete, which seems really
long to me, but it showed no errors.

This happened occasionally months ago and I thought I had it gone after
updateing windows, but is now occuring to the point that the computer is pretty
useless.

If anyone can suggest ideas for tracking this down, or sites than can help with
this process, I'd greatly appreciate it.
