In dire need of help :( (Sound on computer)

Since reformattiong my computer (And losing various .fla’s I thought id backed up :frowning: ) I havent been able to get sound on my computer.

I tried to run a .mov in quicktime and it gave me the error message :

You may experience a problem playing a soundrack in ‘good_text.mov’ because there is no hardware available on your computer. Would you like to close the movie or continue?

I really need the sound badly :frowning:

I have tried installing new drivers through windows update, and right clicking the driver and clicking ‘update driver’. But to no avail. Please say someone can help me get sound :frowning:

I love you all.
