I have a fairly standard 2-year old desktop computer (quad-core intel, single hard drive, decent video card, 300W power supply) which recently started acting up.

I'm not sure what the cause is, so hopefully you can help.

Sometimes (once a week-ish) I press the power button and nothing happens. No blinking, no sounds, no nothing. If I remove the power cord (or flip the switch on the power supply) I hear a capacitor discharge. If I leave it in the "no power at all" state for about 5 minutes then I can put the plug back in and the computer works perfectly.

What is the issue? What do you think I have to replace?
