HT1343 My computer crashed and will not start. My keyboard is on but my monitor will not turn on. I know there is a way to restart the system by pressing both command keys as well as both shift keys along with 2 other letters. I can't remember what those

Can anyone help?

Here you go >  Resetting the PRAM
If a PRAM reset doesn't help, try accessing OS X Recovery.
Shut down the Mac and wait about ten second\s.
Then startup your Mac while holding down the Command + R keys. Let go of those keys when you see the spinning progresss indicator.
With any luck, you'll be able to access the built in utilities to verify and if necessary, repair the startup disk.
