Is the drive seen in the BIOS?
Press F10 (or whatever is listed on the screen at boot up) to access the BIOS/setup screen. Is the drive listed there?
It could be that the drive just died. Three years is a good lifespan for an optical drive that is used fairly regularly.
In the meantime, what are you using for virus/spyware protection? What software for burning? How was your account info stolen? What have you done after this to prevent fiuture occurrences? This may be related or not.
So please respond to all of these questions. We understand you are not a computer geek.
