I had a Creative iNfra 52X which had a similar problem, I discarded the trojan or virus, because it also happened while on the BIOS setup, it wasn't a jumper, because I never messed with them, but I looked for it in a magic book and found the mono azul spell in the CD-ROM trouble section.

I repeated
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul
soy un mono azul

but I finally ended up beleiving I was a blue monkey (strange)
and my CDROM was still messed up

but I found out another spell which said you had to say

soy un pendejo que tiene que botar esta unidad de CD a la basura

1000 times, I did it and It got fixed!!!, I did what I had to do...

I threw it to the garbage!!!

you should say those words.

by the way, I now have a GOOD cd drive, and before i plugged it in, I went to a priest so he could bless it..
