Random Notebook turn off

[Theslowone]

I have a cheap HP pavilion ze4500 that keeps shutting down. It only does it when no one is at it, but it can take anywhere from 10 minutes or a day, but it will just shut down.

Few specs its running windows xp home sp2, 512 ram, celeron cpu, plugged in and batt in.
After we restart it, it sometimes comes up with ipconfig fail error, so we disconnected the cat5 cable from it but still no luck. I have changed all the settings in power management to portray a desktop, but that didn't work either. Norton doesn't pick up anything, and I have all(I think spyware and adware) off of it.

If anyone can point me in the right direction i would be much appreciative.

Thanks.

Just a thought....co-worker with a HP had similar problem....overheating.

use a can of compressed air and blow the unit out...especially the CPU vents....

I think you might be on to something, it is pretty warm to the touch.
