PC won’t turn on after accidentally turned of the switch on the wall

Is the computer plugged in directly to the wall, or is it connected via a power strip (splitter)? If using a power strip, try a different one (or connecting the computer directly to the wall outlet) to make sure it's not the issue. If you're still not having any luck, try connecting some other device onto the outlet (to make sure it's actually working properly and is providing power!) - After you've verified it's not a power strip issue (and that the outlet itself is working properly) try a different computer power cord (just in case you've pulled it too hard and caused internal damage to it), if you're still not having any luck, then disconnect the power cord/strip from the wall outlet, and also disconnect both the main (24PIN) and the CPU (8PIN) plugs from the computer's motherboard, then use either a metal (non-colored) paperclip, or a thin electrical wire (that is stripped on both of it's ends) and connect one end of the paperclip/wire onto one of the blacks (on the 24PIN connector) and another onto one of the greens, now, place the 24PIN connector under a piece of cardboard (for safety reasons), plug the cord back to the wall, and see what happens (the power supply should turn on now, if in doubt, shine a flashlight on it's fan and see if it spins) let me know what is the result of this test and we'll take it from there.

So I did the thing with the paper clip and the power supply started. What could the problem be then if not the power supply ?
Well, it could still be the power supply to be honest (I've once had the same problem, and the PSU also turned on when I hotwired it, but just didn't turn on the usual way, and everything was fine after I changed it) but there are other possibilities too. It could also be a bad power button on the case a or motherboard issue. Reconnect the 24/8 PIN plugs to the motherboard, locate the power/reset wires on the front panel header, and switch between em (this way, your reset button would now be the power button, try using it and see how it goes) if your case has no reset button (which is quite rare), then alternatively, you could disconnect the power button wire, and then touch both of it's pins with a flat bladed screwdriver in order to send a power on signal.

Then you definitely have either a faulty PSU or Motherboard.
And you're gonna have to try a different PSU in order to figure it out.
If you have another desktop computer, you could just take it's PSU for your testing.
Otherwise, you'll have to either borrow one from a friend, or buy a new one (better stick to reputable brands though, such as Seasonic/Evga/Corsair/Antec)
Good luck.

It was for checking if the PSU actually works by powering it up directly (thought it was pretty obvious to be honest)
But as said before, even though it powered up, this is not a clear indication that the PSU is in good working condition.
I too encountered the exact same problem a while back (where hotwiring the PSU worked, but pressing the power button on the case did nothing) and it did turn out to be the PSU after all (I've had a spare one handy, and after changing em, the problem was fully resolved) so it can go either way, PSU or Motherboard.
