I am reasonably compitent with computers, but this is stumping me.

My PC is custom built with AMD Athlon XP2400+ and set up with a dual
boot configuration which has been running fine for over a year without
a glitch, until now.

Now it won't boot either configuration, even in safe mode nor debugging
mode. Everytime it I boot in safe mode it resets itself after the
loading of Mup.sys and hangs in debug mode. I have tried to reinstall
XP but mid way through loading the initial files it resets itself.

I have monitored the hardware in the BIOS for 5 mins and there is no
spike or heat problems with the motherboard or processor, could this be
a hardware problem or is there a way for me to solve this.

Start by testing RAM with memtest86 http://www.memtest86.com/
D/L HDD diagnostics from the manufacture

Could be a number of things. This is what I'd do...

Boot from XP CD into recovery console, run CHKDSK /P.

Test the hard drive with manufacturer's utility.

Test the RAM using memtest and the MS memory test (use both, do several
passes):

Did a search on this file (Mup.sys). Here is a link to some discussions
related to this problem.

Mup.sys is one of the last drivers to load before the Windows gui kicks
in. Seeing it last before a bootup problem does not mean anything in and
of itself.

On many systems, mups.sys is the last listed driver to appear; on some
others, it's agp440.sys - so anything that fails between this and the
next visible thing, gets blamed on mups.sys or agp440.sys instead.

Yes, of course. I'd look at:
- motherboard capacitors (eyeball; may have to remove PSU to see)
- disconnected PSU to motherboard leads, e.g. AGP 4-lead +12V
- bad RAM, using MemTest86 or SIMMtester (free downloads)
- HD file system and disk surfaces, using HD vendor's tools
