My PC is spontaneously rebooting!

Over the last few days, my Compaq has become increasingly unstable, and now reboots occasionally in the middle of things. It can be anything - in the middle of AVG Antivirus 7.5 doing a virus scan, or my kids watching a DVD.

The very first time I noticed something strange was when I inserted my Sandisk Cruzer into the front USB port. Instead of taking a minute or so to transfer files, it told me that it would be something like 1200 hours. I rebooted the system, and next time I inserted the cruzer, the machine rebooted.

The only thing I've changed was about a week ago when I replaced an old DVD-ROM drive with a newer one. In the past, I've also had an additional hard drive in there, so I'm pretty sure it isn't the power supply - there is actually less power usage on it now than it had a month ago.

So, here are the testing steps I've taken:

1) reseat the memory, power and data cables

2) double checked master & slave settings on my IDE DVD burner & IDE DVD-ROM

3) checked all the capacitors on the motherboard for swelling

4) checked CPU temp - running at a very cool 89 degrees F - not surprising for a Sempron with HUGE heatsink

5) ran loads and loads of test utilities from Ultimate Boot CD on the RAM, CPU, motherboard, hard drive. One of the several tests I ran on the USB ports showed a possible problem, the rest did not.

6) I went in to safe mode, removed all USB related items, & rebooted

7) Loaded AVG Antivirus 7.5 & latest virus pattern to make sure this isn't virus related

8) since I've seen it lock up a couple of times using Realplayer 10.5 Gold, I completely uninstalled, then reinstalled. After uninstalling, there was one file left in the folder I couldn't delete until going back into safe mode.

Jury is still out on whether any of this made any difference.

I am wondering if any of you recognize either of these error messages that popped up on my screen. The first one:

http://aycu30.webshots.com/image/11589/2003212579827060620_rs.jpg

Shows what came up after a spontaneous reboot. I would get something about Windows recovering from a serious error, then click on details and get this. The strange thing is, I couldn't even find the described folders on my hard drive to look at the files for more information.

The second message:

http://aycu38.webshots.com/image/14077/2003906891350802289_rs.jpg

I first got while we were watching a RealVideo file. However, later I got it while AVG Antivirus was running, and another time we got it when I was doing something else completely unrelated to playing videos. It seemed to just pop up randomly, and I've never seen this sort of message before.

Anyone have any hints or ideas? Thanks!

P.S. - What really makes this a bitter pill is the fact that I've lost 3 motherboards over the past month and a half. All were ECS motherboards of the same vintage, and all died because of swollen or even burst capacitors. I lost my primary PC in our living room, the one in the basement that we used to watch videos when exercising, and the one I had to use as a backup for the one in our living room, about two weeks after replacing it. Now I'm having issues with the Compaq in our bedroom, even before I've gotten the one in our living room back up and working with new innards. Blegh! It just makes me want to go back to the analog age for a while.

your compaq has a failing hard drive. you can confirm this with what a hard drive diagnostic on the ultimate boot cd. pick which ever one is the maker of that hard drive, maxtor would be my guess. hurry up and get what ever data you need off that drive ASAP is my recommendation on that.

3 mobos dying "swollen or even burst capacitors" points to a power problem. since they were in 3 different computers, in 3 different parts of the house over the last month and a half would say a surge occured and the boards are dying left and right as a result. i dont know if any of your electronic equipment is on even surge strips (hopefully less than a year or two old since they loose resistence to surges/lightning over time) i would recommend UPS battery backups for every computer in your house. once your using that you no longer have to worry about surges/lightning unless something extreme occurs, in which case the UPS will basically sacrifice itself to protect the equipment attached to it. if a surge can get through that, an electrician should check that place out, since it seems like a grounding problem.

its possible the ECS boards you had were all just lower quality or coinincidently did this so close to one another but i think thats unlikely. the hard drive on the compaq i do not think is related to power issues at all, i think its just a coincidence its failing around the same time period as those other computers. how old is all of this hardware that is dying in your house anyway?

~ 7 years old. Still, the only thing going bad was the capacitors. How much does a REAL surge suppressor cost?

the mobos are ~7 years old? they died of natural causes at least, and i wouldnt be bothered about it since thats a decent time for electronics to last. i no longer think it was a surge as a result and think the powersupplies in those 3 old computers.

i would say $20-100, probably around $30 dollars or so for a decent aka real surge suppressor. replace them when they will no longer will pay to replace your hardware under their warranty if the hardware gets zapped due to a surge.

your hardware problems definitely seem to be merely a coincidence that its happening in the 6 week time frame.

Was the a failing hard drive the problem in the compaq, by the way?
