PC reboots when it should shut down

[RICHINMINN]

I built a PC for some friends a couple of years ago. It worked fine for several weeks, then suddenly refused to shut down when you wanted it to, instead rebooting the system. They've lived with it like that since then.

I'm reinstalling Windows (XP Home) on the system, so I thought that I would address the shutdown issue while I was at it.

The system is as follows:
-- MSI K8T-Neo-V motherboard w/ VIA K8T800 chipset (AMD socket 754)
-- AMD Athlon 64 2800+ (socket 754)
-- 512 MB DDR333 or DDR400 memory (I don't recall which, and I don't have the system in front of me.)
-- 80 GB MDT IDE hard drive (generic from 3BTECH.NET)
-- Samsung SW-248F CD/R-RW drive
-- nVidia GeForce2 MX400 video
-- Compaq data/fax modem

I low-level-formatted the hard drive, reinstalled Windows XP Home, installed all of the Windows updates from WINDOWSUPDATE.MICROSOFT.COM, and installed Java, Acrobat Reader, Adobe Flash, etc.

All of that worked fine, though the system still would not shutdown.

I then replaced the cheapy 400W power supply with a better-quality one, but it's still refusing to shut down.

Has anyone ever experienced something like this before?

Try turning off Automatically Restart upon System Failure detection which is on by default. If an error is detected during shutdown, this will trigger an automatic restart. With the restart set to off you MAY get a blue screen to show what, if any, error is detected during shutdown. You may also want to look in Event Viewer for any errors that occur at the time of a shutdown.

Right-click on My Computer, Properties, Advanced tab, Startup and Recovery section Settings button, uncheck Automatically Restart in the System Failure section.

I don't know if you saw this one on wahnula's list of URL's
but This fixed mine, I had a bad card that if you bumped the PC a little it would reboot.

"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.”






This is a Signature and not part of the answer, it appears on every reply.

This is an Analogy so don't take it personally as some have.

Why change the engine if all you need is to change the spark plugs.
