I had one a few months back doing that and all the checks come out clear. I just figured a bad mother board and replaced it. I got tired of fighting a very real ghost. My time and frustration or lack there of are worth more to me than saving a buck or two.

PC rebooting on it's own. Question about electricity/ power, etc.
- Thread starter Walking Man
- Start date
I used to have a small refrigerator plugged into the same circuit as my PC here at the office but it kept pulling too much juice and would create popping noises periodically. It never caused a reboot but I moved it to the other wall anyways and haven't had anymore problems. So, yes the heater is most likely the problem.
Other problems may include:
1. A virus causing reboot periodically. (Does it give you a countdown before it reboots?)
2. Your computer is not recognizing your RAM properly. (I had this problem a couple of years ago and I finally figured out that my computer was looking for RAM in a slot that it wasn't plugged into. So, when I was playing graphic-intensive games, it would need that extra memory but when it went to find it, it wasn't in the slot it thought it was which would cause a reboot. I just moved the sticks around to correct this.)
3. It could be your power supply is going out. (If you have any spare power supplies lying around, you may try to replace it.)
4. Overheating. (Mentioned earlier but can cause reboots if your computer is too dirty.)
Any of these could be the problem but I would definitely check about reconnecting your space heater to another outlet on another circuit before trying anything else as the heater is most likely the problem.

I'm not so sure it's my space heater anymore. It's a actually just frequent enough to be annoying.

How do I do this? I'm using Windows XP Pro.deltaunit said:
Walking man:
there are quite a few things which can cause this..
1) Brown out.. you have a surge protector, but you don't have a UPS or protection from a drop (just excess)
2) loose cables, that may "gap" when heated.. make sure they are all plugged in completly
3) bad power supply - might be dropping out. hard to test this one.
there are some "motherboard" monitoring software (free etc) which you can try out to make sure all the other things are fine (eg heat, drives etc. etc)
it may also be software (kernel) which is even harder.
good luck

What I suggest you do is download SiSoftware Sandra or Motherboard Monitor and post your temperatures and voltages here. This could help diagnose an overheating or power problem.

In my experience overheating generally causes a computer to freeze rather then reboot. This computer overheating the 40'C temps of the summer and froze until I added another fan.
I had one rebooting computer, a P11 and that was a burned connector from the power supply to the motherboard. My money is on not enough voltage. When I brought my computer from the UK I brought a new dual voltage power supply with me. I had it fitted by a local store as I wanted all the cables clipped properly. The tech was very confused when I came back to collect it as the computer was endlessly rebooting, so much so that he was putting a new video card in it. Voltage in shop 120 volts, voltage on power supply 220 volts

To bypass the BSOD altogether and enable the instant "Auto Reboot" feature:
Start/Run/Regedit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl. Right click on "AutoReboot", modify and change the value to 1. Exit, reboot. To disable set the value back to 0.
Make sure all of the microsoft security patches are up to date too. There is an RPC exploit that was fixed a while ago that could cause what you're describing.
