I have a problem that occurs every once in a while. I'm using the professional 64bit version of 7.
I will start my PC and I am unable to see my drives. I can see my 2 HDDs but I cannot see my CD Rom or my memory card reader. Usually I can see everything but once in a while I am unable to see them. Doesn't matter if the CD Rom is empty or not it still does not show up.
If I restart the computer I can see them, but occasionally they are gone. Is this a known bug or is there a fix for it?
