    Oh my, I didn't know I will go on this room. Anyhow, I will explain/narrate more deeply.

    When I clean my Pc totally remove everything and reassemble it back I got power issues and can't figure what's the root cause.

    The previous issue is the computer only starts when I press the power switch but once I release it, the desktop would turn off.

    I tried to replace the power switch and check/unplugreplug the front panel cables- no success

    Check the RAM -nada

    I tried to replace the PSU, it on for a couple of hours then the title of the thread started happening.

    I'm suspecting it's a mobo issue but I'm not sure on that part.

    I have another motherboard but It's kinda old and I don't want to reassemble the Pc since I've done it several times already.

    Here's the Pc specs:

    pull out the board and connect only the power supply, monitor, keyboard and mouse. Be sure to set the board on a non-conductive surface and power it on by briefly shorting the pwr pins on the front panel pin-out, see if it will post (Power On Self Test) that way.

    U could have clean your PC with the compress air with out having to have taken it apart....sounds like maybe something is not connected properly or something was damaged when u put it back together.

    Bad switch is usually the culprit. Trying a different switch might fix the problem.
