Program to test system (power supply)

[mindmeld_me]

I'm working on a system right now and I'm being told it's working funky. It could be a power supply issue but I'm not sure. I can't think of any good test programs right now off the top off my head so I thought I would ask around. virus scan is running on it and nothing bad seems to be listed in the startup list or process running right now. It's a P4 Powerspec so it's a computer system. Seems to be stable right now but I thought I'd run it through the steps anyways. Could anyone suggest a free program or 2 to run for a couple hours to check it out? Thanks for the help

It's a powerspec 9050. It has a P4 3.2 I believe on a MSI motherboard. The system specs are on the website, doing this from memory. It does have 1 gig of DDR SDram which surprised me. a 250 gig 7200 rpm hard drive and a DRD RW and a 52 CD. Also a memory station on the front panel and a 5200 FX Geforce card, also surprising to me for a prebuilt.

I'm told it takes a long time (10 minutes or so) for them to log into the network some days and otherwise some times runs slow or spoty. personally since this is a work system with work people who don't know anything I'm inclinded to say, yea that happens. However the local IT guy didn't want to deal with it thinking a possible power issue or virus and just bought a new one. Shrug, gives me something to play with at work if it looks like I can do something on it. Virus scan is running over the weekend here. I was thinking of running something intensive on it monday to give it a bit of a test.

Haven't gotten around to looking in the Bios to see what the power rails are reading in idle yet, otherwise not to much else I can do aside from pulling the supply out and testing the voltage as you say. Fortunatly I do have the tools. Thanks for any other ideas you can think of.
