I have a HP a320n Pavillion, that has been rebooting itself for the last 2 months. I have been taking it into a service shop, and they have tried everything , as follows, one at a time, to TRY to nail down the problem:

1. swapped power SUPPY, still reboots itself
2. installed a new HD, with all previous DATA "ghosted" onto the new one, still reboots itself
3. swapped out the motherboard, still reboots itself
4. swapped out the ram, still reboots itself

will reboot at home, and at the service shop, on or off the internet. SOMETIMES it can take a week before the rebooting starts.
If I can get the computer to stabilize long enough, will try a HD scan for sasser worm. Failing that, I don't know what else to do.
Any suggestions??
Is there a curse on this thing?There is only one commonality left, and that's the data on the hard drive.
Carry out the procedures listed [highlight]in this post[/highlight] and post a Hijackthis logfile here when done.
If POSSIBLE, zip the logfile and attach it rather than post it.
