Win 2003 Server Restarts after a few days of running

My Router/Game Server has lately been randomely restarting on its own. When I log back into Windows 2003 Standard it says that the system has had a enexpected shutdown. I have looked through the event viewer and I dont see any errors saying a program caused a problem. There also is no memory dump to look through. Recently this has been happening about every 3 to 5 days and the computer is on a UPS so its not a lack of power since my main system has been on for 2 weeks with no reboots.

Could the 350 watt PSU be going bad or is there another possibility? I recently reinstalled Win 2003 Server to see if that would fix the problem and it didnt.
 
The PSU is a Sparkle 300 watt now that I look at it. I will also try running memtest86 and see if errors showed up over time. I did install motherboard monitor and its reporting CPU temp at 76 C but the heatsink isnt very warm and case temp is around 28 C. I think the CPU thermal sensor could be wrong since it works just fine and has been this way for many months.
 
It could be that there isn't a good connection between the heatsink and processor and that is why the heatsink is not warm. Try re-applying some thermal grease. Also 300 Watt is pretty bare minimum now-a-days.
 
List your system specs. Sounds like your heatsink is not mounted correctly if your temp is that high.

You have a thermal problem. There is no reason the CPU should be that high unless the fan died or the heatsink isnt mounted properly. I just did this 2 weeks ago and couldnt get the heatsink to properly seat. My CPU temps would hover around 65C and eventually shoot to over 70 and the system would shut itself off.

I am 99% sure this is your problem. 76C is friggin hot!
 
Tonight when I get my spare 450 watt PSU back I will install that and reset the heatsink with some new artic silver and check the temps again. Hopefully that will solve my random rebooting problem.

My Servers System specs are:

Soyo 7isa+
PIII 1 Ghz CPU
2 Dlink network cards
80 Gb Seagate
Using onboard video
300 watt Sparkle PSU
