It's definitely not the switch. The PC wouldn't have powered up at all if it was bad. Besides, it's just a momentary switch like a doorbell button; extremely simply & rarely ever goes bad.

You're going to have to do some troubleshooting
- when's the last time you blew the dust out of the inside of the case, heatsinks, & power supply?
- the power supply could be failing - putting out enough power to spin a few fans but not enough to power up an entire system
- could be the CPU has failed
- could be the motherboard has failed - check capacitors for swelling or leakage

leaking caps

bulging caps

✔ Best Answer
PC is nearly 10 years old?
If you have 300W power supply lying around (or in your local junk shop) try replacing it.
The coin battery on the motherboard ever changed?
