Simple tests for the power supply:
1. Turn on PC and observe the power supply fan. If it is spinning, most likely, power supply is OK. If not spinning go to the next test.
2, Unplug the power supply's connections to the motherboard, the drives, fans, etc. With the power cord plugged in, short the green wire in the ATX connector w/ any adjacent black wire. This are the same pins being activated by the power switch thru the motherboard. If the power supply fan spins, most likely it is OK. If not, the power supply is dead.

The problem with computer problems like this is they only way to find out the problem is to fix the problem.
On modern computers, the powersupply is controlled through the motherboard. This means the problem could either be in the motherboard or the powersupply.
It is impossible to really determine what the problem is by just looking at the symptoms, as many times a similar symptom could be caused by different problems, or one problem, could cause different symptoms (just like on humans).
The best bet is to bring in the computer, check it, does it work or not, then change the powersupply, does that fix it, then change the mother board, then try changing both. (Once had a problem that was caused by the interaction between a monitor and a video card, change the monitor, no problem, change the video card no problem).

Might have overheated and froze. Is the fan dead???? or maybe it just went into power saving.
Open the case reset the BIOS with the reset jumper. Reattach power, push on. Pay attention to the CPU fan if it is not turning or full of crap it may be too late for the CPU. If it boots your in good shape, but clean out the fan anyway.
If you do find that a component is fried you can get replacements here:

lol this is going to sound strange,
unplug the cord from the back of the power supply. flip the voltage meter from 115v to 220v then flip it back to 115v wait 10 more seconds and plug it back in.
the hang at shutting down windows was just a .exe that had farked up and sat in the background. happens all the time when someone doesnt maintain the operating system.

I guess you have to test it. Use another PSU and see if it powers on...
