system keeps shutting down, need ideas

[SAWYER]

I have an old Pentium 4 desktop that I use as my Windows Home Serve and it keeps shutting down. I can power it on and sometimes it will run 30 seconds, other times a minute or two. I was able to log on to remote desktop and here are some error logs I was able to see

Does Windows actually do a shutdown or is it losing power?

I would check the Power Supply and Processor Heatsink Fan.

 

[SAWYER]

I will try that, and how do I check the ps? it is an Antec Earthwatts 380

I just pulled the heatsink and there was an area without any thermal paste. I evenly smeared it over the heat sink and cpu and put it back on. It has booted up, hopefully that was the issue

Ok it has been running at least 15 minutes but when I try to access it from the network center I can't.
