Seems to be power button problem. Try Replacing Power Button or check the power cable is connected properly.

Get to the power button on the front of the tower and short the switch ...so by-passing the switch and see if it works.

Welcome to TSG....

You say you took the PC apart and cleaned every part? Does this mean you took the heatsink assembly off the processor and the processor out of its socket?

If you did this then there is no hope of us helping you here because doing this makes the processor go really hot and cooks itself and more than likely took the rest of the power supply out as well.

Try a known good power supply. eMachines are notorious for lousy power supply's.

Front panel power switch failures are rare. On some machines it is hard to get to the front panel power switch to "short" it, howver you can unplug the switch from the motherboard header and "short" it on the header.

Have you tried putting a paper clip or similar across the power button or connect the wires direct by-passing the switch and see if the power comes ON.

Check the large capacitors on the motherboard very closely. If you see any bulging or leakage from any of them, you have found your problem.

Before you spend time replacing the power switch, short the two pins it connects to on the MB with a screwdriver. If that doesn't start the machine, it's not the power switch that's the issue.

Short the two pins? just touch them with the screwdriver with power on?

You can connect them first with some wire or use a paper clip with the power OFF....Then turn on the power at the plug and see if it startup.......
