I have a GSA-H31N DVD Drive. It does not recognize any dvd. The problem first started when I tried to install Call of Duty 4. It has now expanded to movies. It see’s cd’s fine. I flashed the f/w with B110 from Dell in the hopes that would cure my woes. No such luck. Any suggestions?

Alcohol or Daemon Tools instaled?

Remove it.

Nope. I don’t have those or anything like them installed. Just the standard player…that used to work.

Call of Duty4 maybe has installed some rootkit/copy protection thing.
