Acer Aspire 7741Z missing CD ROM drivers. Motherboard issue, maybe?
Usually, if the motherboard (meaning BIOS here) goes bad, you will lose all access to all drives. Since the CD-ROM and Recovery partitions have been targeted here, I would say you should be looking hard for a nasty virus or bot. They often attack by blinding your antivirus software, then they disable the CD-ROM (where you would reload from) and the recovery partition (same thing). This keeps them alive longer while you try to figure out what's wrong. I'm not saying that it COULDN'T be hardware or OS related, but first I'd run Malwarebytes or a third party A/V program to be sure that nothing else is wrong first.
