You can flash a new bios, but I'm fairly sure it requires a bios to be working. Are you sure its not just not posting or just going past the f2/12 screen really fast?

yeah the computer boot up but it just ran the cpu instructions i believe it said no bios detected. Also I didn't break the computer neither did anyone else but it was probably something natural

reset it by unpluggging and taking ot the 'coin" battery for a few minutes then try it

after that

You can try flashing a new bios but again I think it requires a current bios, but you may just need a new board

If the BIOS is truly 'missing', usually the chip associated with it is socketed on the motherboard (if not a DIP, then a PLCC).  So you remove, with an appropriate tool, the chip, and insert it into an appropriate EPROM burner. 

 

But I'd be astonished if the BIOS was truly 'missing' on a Dell computer.  Probably some other sort of issue.

What happens if you mash  delete at startup? 

Also what happens if you boot the computer without a hard drive?

As would I, We use optiplex 7xx at my school and thy're like old jeeps, beat up but still running

Although I doubt the pc is worth that level of work
