Does nayone know why my internal cd/dvd rom reader QSI SB241 would stop being recognized at bootup or during windows? 
Someone from CD/DVD reader heaven please help.
i’m having the same problem w/my HP. Have bought every brand of CD, upgraded the driver…blank. I hope someone has an answer…I’ll be watching for it as well.
Thanks so much, Artressa
Maybe the internal connection/cable should be checked…
