CDROM Disappear: Computer Networking Solution

Computer Networking Solution: CDROM drive disappear in BIOS

Computer Networking Solution Scenario:
You are installing FREE AVG on your PC which was working
fine previously with C: and D: drives shown and working well.

Strangely the system lost the D: drive (cdrom) not showed.
You could not access it at all. You cannot see it from BIOS and Windows XP Home control
panel/systems. You also reboot your PC more that 2 times but the result still the same.

You also do virus scan and scan for spyware but no found nothing.

No body opened the tower to tamper with power and IDE cables.

What would you do?

Computer Networking Solution: Basic about BIOS

If the drive is not showing in BIOS, you have a simple hardware
failure. The fact that you were installing a windows based program like
AVG is not relevant. It is just one of those things. BIOS is the
basic hardware detection area of your motherboard, and this level of
device management is not even "aware" that a hard drive exists that
might have Windows on it with AVG installed. That process starts at the
end of Power On Self Test (POST) when the system gets around to looking
at the hard drive to see if it is bootable. But the CD drive has
already been detected (or not) by that time.


Computer Networking Solution to try

You can try to do ‘Cold Boot’, a full electrical shut down.
You even need to unplug the power cord for a minute or two just to be sure
"everything" gets back to a "known state". Totally discharge the electricity from the system

Then Boot to the BIOS.

If it is still missing, and it is set to auto configure,
OR the settings are locked for it to be assigned properly,
you will have to open the case.

Nothing you installed "inside Windows" can make a CD-ROM drive
disappear "IN THE BIOS".

DO NOT open the case if the computer is under warranty as
that might kill the warranty also...

Gently remove the proper data cables and power cables and re-seat
them a time or two. THEN check that ALL cables are seated properly.

Computer Networking Solution : Attention
Anytime "anyone" tells you to open a case, you need to know about
proper anti-static precautions.

Get anti-static "wrist thing", or touch bare metal inside the
case to drain any static charge from yourself while working.
Don't work in an area known to cause lots of "sparks" or "snaps"
(when you walk across the rug, etc... . Unless you are "extra"
careful... (That is hard to define unless you are there...)

If you have a high static area it is better to "stay out"...

Good luck – Computer Networking Solution
