shuttle MN31N keeps shutting down

It's been a long time since I had to ask for help on a computer problem. In fact, I believe it's been a few years but here goes.

i have a shuttle MN31N that I've been using in my server for the past few years. It has an underclocked amd chip in there I believe it is a 2100. Some details on the system:

windows server 2003
I'm running 3 hard drives in it with no pci cards.
using onboard graphics
was originally a refurb bought from newegg
replaced OEM powersupply with something from a name brand company that was more powerful about a year ago

Ever since I received it I would have a problem with it shutting itself down once in awhile. I couldn't run 1 single Distirbuted computing project on it cause it would shut down. Unplug the cord, wait a few seconds, plug it in and then it would work. It would also shutdown during the super hot summer months. Oh and I never run it with the cover on the case cause it shuts down less.

Here's the problem now. New apartment, just moved. Before the move it would go months running fine. Now it runs for a few seconds and turns itself off. I cleaned everything from the hsf to the power supply and got rid of all the dust buildup. Doesn' t seem to have helped.

What is my problem? I'm going nuts not being able to access the content i have on it. I sorta don't want to replace the mobo cause then i would have to reinstall windows.
 
The power supply is the first item I would check or replace. They sometimes don't last very long, especially if your system is left on 24/7. Even name brands fail. You should also inspect the mobo for signs of bad caps. If you want to replace the board, ewiz has the biostar m7ncg micro atx nforce2 board for around $60. If you use the same chipset on the replacement board, you shouldn't have to format. Windows should be able to reload after installing the new board drivers in safe mode.

I agree with the power supply suggestion however, when I originally replaced the power supply I still ran into the same problems with it shutting down or not being able to run any distributed computing programs. One of the first things I check are the capicators. Ever since a string of 5 MSI mobos went bad on me in late 90's early 00's I am always checking those out.

Anyone else have any suggestions? It indirectly points to a heat issue but I'm skeptical of that now.
 
That's a classic PSU symptom so that is suspect#1, try a fan blowing in the side to see if something overheating is the issue. Make certain the CPU fan is spinning and that the nb/sb isn't getting really hot. I used to put copper Vantec icebergs on all my nf2 IGP boards because I didn't like how hot they got.

BTW, what do you have for power conditioning? Oh, and I have one of those in me mom-in-laws system with 1700+ and it has been running like a champ for a couple years now. Don't know what became of the others I built though.

No power conditioning. Brand spanking new apartment. If it would have had issues from the outlet it would have been at my 90 yr old apartment i just moved from.

Cpu fan and the case fan are working just fine. I might want to check the bridges however.
