Hi all, bit of a weird one. Just before Christmas, pc shut off and would not boot back up. Power LED comes on and fans spin for less than a second, then dies again. Power switch then becomes unresponsive until I unplug it, leave it 30 seconds, then plug it back in, which gets me that less than a second of activity. Power supply tester from Amazon shows everything fine with that. Replaced processor and motherboard. Tried the usual moving around of RAM sticks. Removed graphics card and tried booting to integrated graphics.
Any suggestions greatly appreciated because I am out of ideas and can’t afford to just keep throwing new bits at it until it works.
