laptop locks up or gets serious error when using CD-RW drive

I would really appreciate if someone could help me resolve
this problem.

About two months ago I first started experiencing problems
with my Dell Inspiron 4100 laptop when using its CD-RW
Drive. The first evidence was when my system shut down
and displayed one of those Microsoft Windows blue screens,
reporting that my computer had experienced a "serious
problem." I am running XP Home Edition. The laptop
worked well other than when trying to use the CD drive, at
which time the system would often lock-up. After numerous
phone calls with Dell and several attempted solutions
(e.g., system restores), a technician resolved that the
system was experiencing a software problem and that I need
to reload the CD software. I did so with Roxio Easy CD &
DVD creator version 6, and the problem disappeared for a
few days.

Then another problem came. When I would put a CD into the
drive, the drive would not recognize the CD at all. After
another go-round, Dell technical support told me that my
CD-RW drive must be bad, so I purchased a new Dell CD-RW /
DVD combo drive. This drive experienced the same
problem. Fortunately, I was able to send it back.

I then took my laptop to a local technician since the
laptop is about 16 months old and out of warranty. The
technician reinstalled Windows XP Home Edition, and again
the system seemed to work fine for a few days. Then, my
computer started locking up again when using the CD
Drive. I got a blue screen with the following error
message a few days ago:

BCCode : 100000ea BCP1 : 81268680 BCP2 :
815F3008 BCP3 : 81788B38
BCP4 : 00000001 OSVer : 5_1_2600 SP : 0_0
Product : 768_1

More recently, I got the folling Windows error signature:

BCCode : 100000ea BCP1 : 813C0520 BCP2 :
81374150 BCP3 : 817666A0
BCP4 : 00000001 OSVer : 5_1_2600 SP : 0_0

Some important things to note are that the laptop works
fine when not using the CD-Drive. For instance, I can
remove the CD-Drive and put the floppy drive in its place,
and there are not apparent problems. Also, as I've
experimented, I've noticed that the computer seems to lock-
up or get an error when I try to move the cursor (using
the touch-pad, pointer, or serial mouse) when a CD is in
the drive. If I don't use any of these devices, the
computer doesn't seem inclined to lock-up. For instance,
today I played the first three tracks of a music CD with
no problems, and the system did not lock up until I tried
to use the mouse.

Thanks for your help!

Sincerely,
Dave
