PS3 not accepting discs (80 gig)

[Mianrtcv]

Just when I don't need another expense, one just may have presented itself. My 80 gig Playstation3 is not accepting discs. It is not under warranty either. I have not used it for online play or web use. However it seems to boot up and powrs on to the normal screen.
I know there is no disc in it. It does not accept discs at all. It does not engage when a disc is put in the slot. When you go to put the disc in it just stops. If you hit eject it just beeps as is standard when there is no disc. 1st an xbox bites it. Now this. Any help would be greatly appreciated.
