Personally, 5 years is nothing in the life of a power supply, unless it is overloaded.

What’s the wattage (ha) of the PS?

Look in syslog and see if it says anything interesting (syslog, messages, whatever).

Do you have lmsensors installed? Does it show anything bad?

I'm thinking this is a darktable thing as it has been 30 minutes since the restart and when it was restarting it went about five minutes. Any ideas as to what to do?

The computer keeps shutting itself off. :(

So I remembered that I had a blower for this and I blew it out and we'll see what happens. The funny thing is that it only seems to do it after I start darktable. I am guessing that it is because dt uses the cpu more. I don't know..... Well, we'll start darktable now and see what happens..... darn. it shut itself off! so this does sound like the power supply?
