Windows XP Reboots instead of Shutting down?

A friend of mine has an old Pentium 2 based system which he has just installed XP pro on. The problem is that when you shutdown, instead of turning off it reboots. It worked at first, but has now stopped working. I have experienced this myself with older machines but never attempted to sort it. Does anyone know how?

Thanks.

 

if i'm correct the problem is a power options setting.
set it to desktop/home/office pc and it should turn off fine.

 

Thanks but it's something a bit more than that I think

 

When XP crashes, i.e. BSOD, it resets itself immediately so you don't get a chance to read the error message, so perhaps the machine is crashing when you shut it down.

You can disable the reboot on crash by going to system properties, advanced tab, startup and recovery settings, and unchecking "automatically restart".

Although obviously that's not necessarily the reason your friend's machine is rebooting automatically, but if it's BSODing then you'll see it...

 

Sometimes it's a problem with APCI (ACPI?) dont remember the exact wording but I've seen bios and OS updates that fix the problem.

 

I indeed have had the same problem

I found out what was causing mine, i have a creative soundcard and XP took a disliking to it. So i had to get the up to date drivers off the Creative Website and since then No Problems
