can't see CD-Rom drive, and ZIP drives, both missing from "my computer"
found the Secondary IDE controller on "Hard disk controller" had problem (yellow error sign)
-- set "both IDE Channels enable" from default in the PCI BUS MAster IDE controller, and restart the computer will fix one of the problem -- after restart the PC can see ZIP drive in "my computer", but still CAN NOT see CD-rom drive.
And later, the ZIP driver will disappear again from "my computer".
What was the cause of the above problem? I suspect - some kind of Virus?
If that is the case, what kind of Virus? How can I fix?
If not the Virus, what kind of problem may be?
How can I fix?
I Appreciate ALL of your kind help!
