Its ok mate

I apologise for my jumping on ya case
It does not sound like a driver problem at all more maybe a faulty Optical drive
Maybe a faulty cable? Is it an IDE or SATA drive?
chkdisk is run by entering into RUN/CMD
in command window type chkdsk /f
this will then tell you chdsk cannot be run while system is running do you want to examine drive on reboot
type 'y' and enter
Reboot your machine it will then run a diagnostic of your main drive. It could take a few mins.
After unning it will start O/S again
Your chipset will be written in the manual if you have it.
