If I put in a cd and start the computer it will see it and try to load off of it like it is working fine. Then I start windows and try to use it and nothing. I check and the drive isnt located and has the yellow exclamation point with code 41 saying the drive isnt located. I tried my new drive from my other computer and same thing. Thing that gets me is it works on start up and will boot off of it so I know the drive isnt dead. Please help.
