Hello, I believe the power switch on my computer has become disconnected from the button. It’s a gaming pc and was hand built. The problem is I cannot access the area where the power switch is located to try and make sure that’s the problem. The mother board has power, the CMOS battery was changed and the computer turned on only one time after all the at home fixes I tried. I turned it off after 2 days for a windows 10 update and it now doesn’t turn on when I press the power button. So I think its the power switch with it being a prebuilt and maybe being rocked or something by the cats. They inside of the pc is dusty and I can clean it before coming in.
