Check to make sure the power supply switch is "on" (not just the case 
switch). The power supply switch is located on the power supply close to 
where the power cord connects to the computer.

After checking the power supply switch, when you push the case power 
switch, does the power supply fan come on, or any lights on the case or 
keyboard come on, or any noise at all from the computer? If there is 
some indication of life, post back what is happening, so you can get 
further assistance.

If nothing at all happens, there are two likely causes. One - the power 
supply has died. Two - the case power switch has gone bad.

In either case, you will need to open the case. Make sure you follow 
proper grounding procedures when working inside the case. Since the 
computer is a newer model, with the power cord connected and the power 
supply turned on, there should be a small green LED lit on the 
motherboard. If not, it is very likely the power supply is the problem. 
If the LED is lit and nothing happens when the case switch is pressed, 
you need to disconnect the wires for the reset switch and the case power 
switch from the motherboard (refer to the manual) and connect the reset 
wires where the power switch wires were connected. In essence, the reset 
switch will temporarily be used as the power switch. ***Opinions differ 
on unplugging the computer while working inside the case. I do while 
changing any wire connections to the motherboard and other times I 
don't.*** With the power connected and the power supply switched on, 
press the reset switch. If the computer starts up (fans, hard 
drives,etc.) than the problem is very likely the case power switch. If 
nothing happens, than the problem is very likely the power supply.

The power supply is easy to replace. There are many retailers who sell 
power supplies. For power supplies I use newegg.com. They are a 
topflight dealer with a wide selection of power supplies at very 
reasonable prices. I would get a 400 to 450 Watt power supply to allow 
for possible future upgrades to the computer. The power supply is 
normally held in place with 4 screws. If you have a cramped case, the 
hardest part of the replacement process will be having room without 
removing other components, or at least not too many. Study the existing 
power connections (take pictures) so that you can redo the connections 
with the new power supply.

I hope this helps. If you have any other questions, just post them.
