Yeah my dad suggested the outlet could just be bad/old itself and to try using it in another room for a few days.
Plug an incandescent bulb into the same duplex receptacle. Does it dim to less than 40% intensity? If not, then AC power from that receptacle is just fine.
Remove those surge protectors. Those do nothing useful. If problematic, this a bulb powered by then will dim that much. What do those protectors do? Nothing until 120 volts rises to something well above 330 volts.
Your computer power is determined by a power controller. it decides when a PSU can power on, when it powers off, and even when the CPU can execute. Even the front panel button is only a request to that controller. Controller sees the button pressed. And then decides what it wants to do.
Your solutoin (and every informed reply) is a complete discussion of what that controller sees and why it does what so concerns you. Until you provide numbers that the controller is seeing, then nobody can recommend anything honest and informed. You must first provide hard facts. That means a digital meter, request some instructions, and perform maybe two minutes of labor.
Otherwise just shotgun. Ignore any reply. Select what good part to replace next. Keep doing that until something works.
Those are your only two options. First one is based in how computers work. Second is based in wild speculation.
