I have had this problem twice before. Both times I found that the CPU fan would cut in and out, the processor would heat up, and the machine would shut down. On one paticular machine, the fan worked, but was slowed down because the o-ring broke off and the fan was pushing against the outside of the rod. It was enough to keep the CPU cool for only about 1 1/2 to 2 hours before the machine would shut down.

I would check the Power Management before I suspect the power supply . Does your computer completely shutdown or does it go into Suspend mode . See the hard disk and power LEDs etc . Most probably it is the power management . You can check it in Power applet in Control panel . Also there might be some power saving feature setup in the Bios Check it out before moving forward .
Good Luck !

To directly answer your question. Get yourself a digital Volt Ohm Meter. I use a Fluke 87 because it has a logging feature that will remember the minimum and maximum over a period of time. I have found flakey (they will drop out for a bit and come back.) supplies this way.
