    Hi everyone.

    I've had a problem lately with my PC suddenly losing power. It then tries to start up again for a second, but then loses power. A second later it tries to boot again, then turns off again. The case fans spin each time. Only the CPU fan doesn't go. The GPu lights up too. I've had success fixing it by either wiggling the ATX connector or unplugging it and plugging it back in, but that didn't work this time.

    I think I've narrowed it down to the slot where the main PSU cord plugs into my motherboard.

    I had pretty much everything else unplugged and it was failing to start up. Then I put my old PSU in and it worked right away. After that I put my normal PSU back in and it worked right away after that. I think there's something wrong with the slot because I noticed one of the pins don't look right compared to the rest. Here's a pic. Sorry if its hard to tell, but that indicated pin looks different:


    I'm assuming that as the parts heat up that it loses connection or something. Is this one pin something I can clean somehow? I don't know why switching PSU's then switching back made it work again.
