I think this is the correct forum??

 

I thought I would mention this for the less technically gifted amongst us including me!

 

So must have had a power failure during the nite. One of my PC's would not switch on again. The green light on the back, however, was on.

 

 

 

To fix it I had to remove the power cord and the 24pin that goes to the motherboard hold the power button in for 30 seconds then leave for 20 minutes. When I went back it worked ok. Now whether the order of the above things makes a difference or not all of the things helped all i know is the pc is up and running again. Hope it helps someone else

I've found a number of times that a PC that won't turn on requires the power to physically be disconnected and then just wait.  I suspect that there's enough power going through to hold the trip circuit on.  Similar things can happen with devices that have a thermal trip.

Yep, check that fans and grilles are all dust/dirt free else could happen again.

You have basically described resetting the BIOS by disconnecting/draining the CMOS battery and the capacitors on the motherboard. 

 

( the removing the 24 pin was probably not needed- just unplugging the IEC cord would do it when combined with the "long press" on the power button, )

 

Although the fact that 20 mins of being unplugged likely drained the CMOS battery indicates that it could be due for replacement,
