Hi;
My PC (ATHLON XP 2600+; Win XP PRO OS) is rebooting by it self after selecting the “Turn Off” command (similar to “Restart” selection). I have to push the main switch to OFF on my Pwr. Center before it starts to reboot again.
This problem started only recently and I do not know why.
Is any one familiar with this kind of problem???
Please let me know.
Thank you; Bill

i am not farmilliar with that problem, but since you are running windows xp you could try restoring it to an earlier point to when the computer didn't do that. to open the restore utility you have to go to start, then all programs, system tools, and system restore. then click on restore my computer to an earlier time, then select the date when it worked correctly (you can only select dates in bold because those are system checkpoints). Then the computer will reboot and be set back to the time selected. when you restore your computer using the restore utility you will not loose any recent files or recently created data. It will only undo system settings, programs, etc. Also any change that you make using the restore utility is completely reveseable. just go back to the sys restore and click on undo my last restore (only visible after you have used it before). i don't know if this will fix that specific problem but it's worth a try.

Thank you Kevin; I tried the restore command, it didn't work.

Bill,

This sounds like a hardware problem to me. It could be power supply or motherboard related. Go into the BIOS or "Setup" option during startup, and check your voltages. They should be withing %5 of spec. If not, you need a new power supply. Next, try and reset the CMOS on the motherboard. There should be a quarter-sized lithium cell on it. Take it off for at least 10 seconds. Reboot, and use default settings if you have to choose any.

I hope it helps.

Thank you for your reply.
I already changed the PWR Supply and reset the CMOS as well- NO help... :o(
I am using MoBo monitoring software which is including Voltages - with out of range alarms.
On this PC I am running dual OS (Win XP & Win 98 SE) - Hard Drive selectable.
The Win 98 is operating OK, which may exclude the hardware conflict/problem (???).
I am almost ready to accept this nuisance because otherwise the PC is OK.
Best regards; Bill

Self reboots were common back during the interim period between ATX and AT boards. Some were not ready for the self-shutting down windows 98 or XP. This is usually traced to an incompatiable APM (Advanced Power Management) in the BIOS. Try disabling APM in BIOS and see how it reacts.

Also try this:

Disabling the “restart on system failure” feature may permit the exact cause to be isolated: Right-click on My Computer, click Properties, click the Advanced tab. Under “Startup & Recovery,” click Settings. Under “System Failure,” uncheck the box in front of “Automatically restart.”

I've had my fair share of incompatable BIOS' when trying to integrate OS with hardware. Particularly with cheap, bargain basement mainboards like PCchips. When I do buildups I go with brand named boards that I know from reputation from forums to be proven performers, ASUS, MSI, Epox, Gigabyte, and ECS, just to name a few.

HTH!
