Hello. My problem is that my computer will not start up. I built it years ago and it just shut off and wouldn't power on. I bought a new PSU, I knew the original one has a few hick ups and was sounding rough. It works if I do the short with a paper clip trick. Took everything off the board and left only the processor and HSF. (Following the checklist I found on this site) Now I flick on the power and - here's the issue - the fans turn for less than a second and the front light turns on but then nothing. I don't think its on for long enough to even post or anything. Haven't run into this issue before.
I had a spare board in the closet so I tried again and same result. What is going on here? Any ideas?
