Which items do you know - without doubt - are good? If the list is empty, you have done lots of work without any accomplishments.
Your solution starts with collecting numbers - not changing anything. For example, what are the voltage in the purple, green and gray wires (from power supply to motherboard) both before and when the power switch is pressed. You currently have little idea how much additional facts are in those numbers. Post them so that others with significant experience can report those numbers.
Also critical are voltage on any one red, orange, and yellow wires when the system is fully loaded. Prime95 does provide a maximum load - is not sufficient. A maximum load is when you are playing complex graphics (ie a movie), while downloading from the internet, while playing sound loudly, while searching the hard drive, while reading a CD rom, while powering a USB device, while ... Multitasking is the heavy load - not Prime95. Now measure any one red, orange, and yellow wire.
Those numbers from six wires will result in answers that are definitive. Then you have items on your list of accomplishments.
Do not swap any parts or change any voltages. Leave everything as is. First collect the important numbers. If your computer is from the more responsible manufacturers, then execute the comprehensive hardware diagnostics that execute without Windows. More information that combined with those voltage numbers may even identify the problem in the very next post. Again, you don't know how much information is in those numbers - yet.
Your power supply must output the same voltage when AC mains are at 260 volts or at 180 volts. All those voltages are ideal to every computer. All those voltages cause no change to the DC voltages. Anyone who did not know that would make silly recommendations such as plug it directly into the wall. If your power cord was causing low voltage, then it is also a fire hazard. Ignore the myths. Get numbers. Post them. Have a useful reply immediately.
