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? -- :-)~MIKE~(-:
