Re: no booting or nothing
Narrowing down a fault like this is relatively easy but time consuming.
Please read this thread about building your machine outside of the case. http://forum.pcmech.com/showthread.php?t=132409
The idea of an "out of case build" is to reduce the amount of hardware in order to eliminate what is causing the problem.
I build computers eveyday and I still use this method from time to time when trouble shooting.

Hmm. I wouldn't have thought it had anything to do with pressing the button. It sounds more like a failing power supply or lack of current for startup. Did you make sure you plugged the power into the video card power connector (if it has one)? I know it worked ok at first but a heavier load can cause older or under-rated power supplies to fail soon after. Just a thought.
When you press the power button do you hear the fan running, hear the disk drive running, see any lights, do you hear the cd drive click once and see the light come on briefly on the cd drive door? If you see all the aforementioned then it is surely trying to boot. Computers don't boot mainly because of the following problems. 1) Bad Power Cord or Power Supply. 2) Electro Static Buildup. 3) Bad Motherboard 4) Bad boot or system files. Remove the Power Cord and the battery if it's a laptop. Press and Hold the Power Button for 30 Seconds. Then replace only the Power Cord and try hitting the Power Button. If it boots you had an Electro Static Buildup. If you have boot or system files that are missing or corrupt normally the system will be telling you that on an error message that appears on the screen. Does your system show you anything on the screen when you press the Power Button? If not you have a Power Supply or Motherboard issue.
Unplug everything from the laptop, remove the battery and let it sit for 5 minutes. Replace the battery only, not the power brick and see if it will boot.
Does the power brick have a solid green light? Flashing? Red?
If it will not boot off the battery or power brick it may be fried.
It sounds like it's probably the power supply. Computers require more power to boot up than they do to keep running, so if it's fine once it gets going, the power supply may just be dying. If you have a multimeter and know what you're doing, you can test the power supply connectors to see if any of them (especially the ones leading to the motherboard) are not giving the proper voltages.
There are numerous issues that could cause this but if absolutely nothing happens, no lights, no fans, nothing then check the power supply. Use a simple voltage tester to see if you have any voltage on the connectors going to the hard drive and cd/dvd drives. If not this is a pretty easy and relatively inexpensive fix.

If you can try tapping F8 repeatedly, sometimes it will give you choices of boot devices, so just choose your primary hard drive press enter and tap F8 again until you see the Advance Boot Menu, choose safe mode and see if you can successfully boot into it.
Once in safe mode click on Start>Run then type in restore. Anew window will pop up. double click on on rstrui icon.
This will now launch the System Restore window click on the radio button "Restore my Computer to an earlier time" and press enter. A calendar will show you the available dates that you can restore from. Choose the day you know that your computer was stable. If your computer still wont boot up do the same procedure and choose another date. "NEVER GO BACK TO MORE THAN 30 DAYS UNLESS YOU ARE OUT OF OPTIONS"
Hope this solves your problems don't worry this is just the 1st solution there are many more.
