Hello, I have a strange problem.

I unscrewed my computer to see which PSU I have. Afterwards it would not turn on.

I got an old computer and took its PSU and connected it to my computer, it turned on.

Then I took the PSU from my computer and put it in the old one and it would also turn on.

Yet when I connect my PSU back to my computer still nothing works.

What could be the problem? Thanks in advance.

What do u mean by "it would not turn on", is it u r stuck in BIOS ? or the hardware is not starting up at all ?
