Today may 3 year old macbook pro froze just after it had finished starting up and loaded itself ready to go (all the desktop etc). The mouse froze in place, couldn't do anything! I gave it a few mins, still froze. So i forced shut it down with the power button. Left it a few mins then, pressed the power button to start it. The light came on immediately and i could hear it running, but the screen didn't come on, it didn't make any of the usual machanical noises either just started running straight away, it wont accept discs either Its now a month out of its Apple Care Warranty as well Can someone please help me?!
