Had my PC for a fair number of years but still does the job. Today it randomly turned off without warning. I thought it was a powercut but wasnt.
Anyway it turned back on ok but did it again 15 mins later. I looked in Event Viewer and no errors there. Scanned the HDD no errors and temps all look normal. So my guess is power supply. Anyway to know for certain without replacing it? Dont want to pay to replace it only to find its something else
Seems odd that it works for abit before turning off. If it was power supply i would have thought it would refuse to turn back on?
Yes, I would agree that a PSU fault would mean that the PC wouldn't turn on again. The slow shut down could be related to a HDD issue. Does a BSOD (Blue Screen Of Death) appear before the PC shuts down, or does it just shut down instantly?
