Computer reboots all the time

I have an older computer purchased in 2000. It worked great until the Spring of 2005 when it started to reboot spontanously every 5 to 10 min. This became progressively worse until it was difficult to use the computer so I took to the shop for repair and they told me the motherboard was shot.
Below is the sequence of work I performed on this computer and to no avail it is still re-booting.

I changed the Motherboard & CPU which I purchased used on e-bay so it's the same one that was in the computer before an Abit VH6 & CPU 766 mhz

The hard drive is a Maxtor 15 gig which I have done a diagnotic from Maxtors website and a low format. The test showed the hard drive was good.
I changed the CD-ROM drive for another one.
After doing all of this I tried to install Windows XP but I only got as far as "Windows setup copies files to the Windows installation folder, your computer will now reboot" which it did and then it kept on re-booting without completing the final installation. I then tried Windows 98 and I got a bit further but once the system rebooted it kept rebooting. I can't think of anything else to try.
Hopefully someone may have had this problem before and can help!

I forgot to mention, I also put another brand new power supply from another computer and it still kept re-booting.

Seems silly, but have you checked for dust build up in the heatsink?

Yes, I have all the dust cleaned out of the CPU fan as well as the power supply fan.
Tonight I noticed, that when I touch the metal part of my case there is a bit of electrical current going through, even if I unplug the computer but leave the monitor pluged it, I still feel the current. The only way to eliminate this is to also unplug the monitor and the computer. I tried another monitor and it did the same thing.

If you are feeling electrical current coming through the case, you definitely have something shorted somewhere. Likely candidate would be a motherboard standoff. While you have the motherboard off to check that try the out of case procedure in this thread. That will determine whether all your core components are functioning correctly.
