|Wife's computer is power cycling repeatedly. When it gets turned on, it starts to spin up and then shuts off, then tries again, and shuts off. Over and over in a one second loop. No beeps or any other unusual sounds (grinding fan, etc). Just starts the fans then dies after a second and then tries again.|
Thinking it is the power supply as it isn't even on long enough to start anything else. Any thoughts before I open it up when I get home? Gonna blow out the dust, but I suspect it isn't dust (not that old and off the floor) and even if it was dust, I'm thinking damage is done so removing dust likely won't help. The power supply light on the back is green, so in theory it is receiving power.
Any thing else I should consider if it winds up not being the PSU? I think I have a spare PSU, but if that doesn't work I will be at a loss as to what to try next.
Thanks in advance!
