The info you supplied may be of some use later, but you have not provided the info about what is wrong now.

Ask your son to show you exactly what he did, without him actually doing anything that changes settings.

Your problems have probably got nothing to do with the bios, unless your son entered the bios Setup while booting and fiddled with settings there and then Saved the changes.

"he put a cd in cd rom and it came back as a reading error press ctrl+alt+del but the computer would not ressart"

Is the CD scratched or dirty ?
Do other CDs read fine in the same drive?
Is there more than one CD or DVD drive?
Did he click on the drive letter for the CD drive and that's when he got the message it can't be read?
If you have more than one drive and he clicked on the wrong drive letter, and it had no disk in it
or
if he inserted a DVD in a drive that can't read them,
then it's normal to not be able to read the disk.

"CDs" and "DVDs" are both compact disks and look exactly the same physically, but DVDs hold a lot more data, and the data tracks on a DVD are much finer and closer together. You can read "CDs" in a DVD drive, but you can't read "DVDs" in a CD only drive - CDRom, or CD-RW, only.


When you get a message to press Alt-Ctrl-Del to restart the computer, the computer sometimes won't restart when you do try that.If you can't do anything at that point, you hold the power button in until the computer shuts off, or switch off the AC power to the computer, switch it back on, then boot normally.
If you then see a blue screen where it says CHKDSK wants to run while booting, let it run - don't press any keys until that's finished. It should not want to run after that when you boot.

You info is too sparse.

You did not mention that your computer does boot the mboard itself and you had video previously. You should have told us that in your first post.

The computer not booting at all is different problem from
- the computer booting and having video but not finding a bootable hard drive,
- or it does find a bootable hard drive but Windows won't load normally.

Which situation do you have ?
......

Is the bios not finding a bootable drive, or similar,. while booting?
If yes,
Go into the bios Setup and load bios defaults.
That's probably either on the first menu you see when you first go into the bios, or it's on the Exit page or similar.
Save bios settings after you have done that. The computer will then reboot.

If doing that doesn't get the computer booting normally, tell us what you see including messages, and we can help you further.

It's BIOS or CMOS Setup utility, cmos being the part of the bios you can change some settings in yourself.

Those things are normal, if you have no IDE hard or optical drives connected, and you have a SATA hard drive and a SATA optical (CD or DVD) drive., connected to the SATA headers for the SATA primary controller - e.g. SATA I and SATA II .
......

"ATAPI DVD A DH16A6"

"DH16A6"

Did you copy that correctly?

E.g.

Lite-On
DH-16A3L, DH-16A3S, DH-16A3H, DH-16A3P

Dell XPS 730, with a PLDS DH-16AS

Lite-On made optical drives supplied to Dell - the model may be slightly different from Lite-on's retail models. The same models sold to Dell may have been sold to other brand name builders or as a cheaper OEM bulk model (a drive in a bag, without or with burning software, if the drive can burn disks).


That drive can read both DVDs and CDs, but it may not be able to read newer types of DVDs.


Optical drives don't last forever.

DVD drives have at least two lasers and associated circuits. Sometimes after the drive has been used a lot, one laser or the circuits for it burns out or malfunctions - in that case, the drive can no longer read any DVDs, or can no longer read any CDs.

Even more common is eventually the sleeve bearings in the drive's motor deteriorate to the point the motor can no longer spin at even the minimum 1X standard audio CD speed, or it may stop spinning completely.

Defective optical (CD or DVD) drives can cause all sorts of strange symptoms.
You could try removing the AC power to the computer - unplug the cord or switch off a power bar or whatever the cord is plugged into.
Open up the case by removing the left side panel as seen from the front of the case. Unplug the SATA cable that goes to the DVD drive, from the drive, make sure that end is not touching anything metal.
Restore the AC power and try booting.
