|So, go ahead and hit the delete key and reset the BIOS to default settings. The BIOS should beep once if the problem is not hardware. If it detects hardware issues, it should give a message or beep a probem code. If it doesn't beep, it may be the beeper is disabled or damaged. |
If you hear a single beep right after the BIOS post, meaning the BIOS checksum was successfull, the problem is most likely in the Operative System.
The CDROM not booting may be due to device damage so disconnect it from power and data cable. And while you're removing the CDROM connections, check the Hard Drive connections for snug fit.
During the BIOS post hit the Pause key on the keyboard so you can read everything the BIOS does and detects so you can have a better understanding of the problem.
