Bios not responding and unable to boot from CD/DVD

[bootneck02]

  Help I am running Vista Premium on my home built PC and if I can chronologically go through how things happened.
1) the PC stopped restarting via the software restart button and I had to hard reboot via the reboot button on the PC.
2) My Computer showed that I had a floppy which I have not and the BIOS also showed first boot disc was floppy and even if I tried to delete from software and changed BIOS to CD it reinstalled on Vista and changed to Floppy in BIOS
3) Now cannot boot from CD so unable to reinstall Vista or any other OS or Bart XP so cannot reformat disc.

I have thought about the problem and the only solution I can think of is to remove the C drive from the PC and put it into a HD enclosure, connect to my XP PC and reformat from XP. Then take out the battery from the Vista PC and short out the mother board, replace battery and reformatted C drive then reinstall Vista. If any one can see another way or can give advice I would only to pleased to here from you. If I have posted in the wrong place sorry but not sure where to post it

Pretty drastic measures at this point...
What happened that caused the Vista install not to boot ? ?

I would power down and remove all power.
Then replace the CMOS battery (which i don't think is the culprit but they're 2 Bucks (.
Then on first boot enter Setup and set the boot order to CDROM then HDD.
Press F10 to "save changes and exit".

Then boot up normally and see where this takes you...

 ::)Thanks for the reply patio one thing I forgot to mention is that BIOS will not register key strokes I am at a loss with this one, it would that somethin has corrupted the BIOS and Vista and I have fire wall anti virus and anti spyware.

There are very few BIOS infection agents out there...if any.
Borrow or buy a PS2 keyboard and follow the steps.
Everyone should have one...even if it sits in the closet all year.
