As the title says, the computer will turn on for about 5 seconds then turn itself off then back on to only turn itself off/on again at the same rate.
I really doubt any components are faulty since this isn't a new build and it only occurred after blowing dust out of it which I regularly do. Already checked loose connections and reseated most of the components and nothing seems to make a difference.
Not sure if specs matter but:
exactly my line of thinking actually. just wanted to see if anyone had any other ideas before i reseated every connection for the 20th time.....which in fact i did and that seems to have resolved this.
