Read about the dangers of Universal Plug and Play at Steve Gibson\'s website uhh, i thought that was fixed years ago...

The latest "fix" for uphphost was implemented in March of last year. See https://www.microsoft.com/technet/security/Bulletin/MS06-011.mspx for details. Windows products are constantly probed for vulnerabilities, so it makes sense for me to disable the unnecessary services. Dramatic, perhaps. But I find comfort with that level of caution.

That's because HP and several other manufacturers shipped machines with unsupported configurations. Microsoft posted an updated version of their warning against using the practice the same day SP3 was released for general distro. This is not new. The same thing had happened with SP2. web page Unlike the mess Microsoft created with Vista SP1, this thing is not their fault.

Did you say you've done a clean install on the OS?
That's the only way to eliminate the possibilities of it being software related.
Also, a "rebooting PC" can be a sure sign of any number of viruses which create symptoms such as that.

Another possibility, in my experience, is that the Motherboard Capacitors are going bad. Look at the caps around the processor to see if they are "bubbling up".

Heat... open the box and use a small fan to cool MB ,CPU, memory and video.
Also remove all cards clean contacts and reseat.
a flaky powersuply will cause pc's to reboot.

So I'm back from vacation and the PC has been continuing to reboot. Following Dagwoodsystems excellent advice I've been checking the event monitor, but to no avail. The system reboots and there's no message.
To date I had resolved two problems - a bum Cd/DVD drive that caused a reboot when accessed and a problem with Zone Alarm's True Vector software (that also caused reboots).
At this point the POS PC has been rebooting with no indications as to why every 2 or 3 hours. I've tried everything else at this point so maybe it's bad memory. I downloaded Microsofts memory test and ran it for five straight hours (booting off a floppy)- no problems & no reboots.
I opened the cover and ran the machine with a fan pointing at the system. It crashed. I cleaned the contacts on the cards and checked the condensors on the mother board. It crashed.
By now I was really ticked off. I went down to the dreaded basement and grabbed an old PC and stripped out the power supply.
Now people have been suggesting a defective power supply as a problem for a while, Kevin G most recently. I was a little hesitant for a couple of reasons. First, I'd changed the PS 2 or 3 years ago and installed a larger, "better" unit and second, when I'd booted to an "A" prompt with a floppy (two separate times), the system never crashed.
But it was this or buy a new system so I swapped out the power supply. The existing unit was a large 430 Watt model and the one I had grabbed was a paltry 300 Watts, but what the heck, let's experiment.
I only hooked up one of the 3 hard disks in the unit (I'd already disconnected one of the drives during previous troubleshooting). I figured the Mac is my new primary system, if I can get the PC to work it'll only be for the things I CAN'T get running on the Mac (Visio, Spider Solitaire [the easy version from MS], dBase, Easy Bridge etc.) so one disk should do it. I'll back up whatever I need to an external USB drive.
I threw the PS in and lo and behold it's been running for over 30 hours without a blip. Maybe HD #2 is causing problems? Nah,it's the PS.
3 simultaneous, different problems in one machine. Go figure.
My thanks to everyone who has helped me in this endeavor, especially Dagwoodsystems without whose help I never would have found the True Vector problem. (Now I've got to call ZA and ask them what they have to say for themselves!).
What a great bunch of guys (and gals!) here. What a wealth of knowledge! This place is awesome!
Thanks again,
Sam
