Hi. I have been using my laptop for a long time now, mostly neglecting my desktop. I've decided I want to use the desktop again. It is not a bad desktop, even though the last time I upgraded it was a few years ago, its still pretty darn good I would say.


My problem is it has been very abruptly and completely shutting off. I was trying to update the video drivers and with nothing else running, it would get about halfway through the installation process and BOOM. The computer is off. no error messages pop up, the fans dont make excessive noises, it just stops.


I checked all the physical connections and everything seems fine. there is minimal dust in the fans, though I suppose I could still blow it out. The fans all seem to be pretty normal sounding.


I can't figure this one out. It isn't like I am doing anything intensive.


Could I need to replace the power supply?

Sounds like a good possibilty it is the PSU, ways to test it i believe with a paper clip, unless have a spare one, kind of hard to know, be first place i would check. http://www.wikihow.c...-a-Power-Supply

Unless have meter you can check it that way  http://pcsupport.abo...-multimeter.htm


Be careful ground yourself when working inside a PC touch metal surface on exterior of frame PC, push power button in a few times to discharge electric from unit first.
