I turn my computer on, and about 5 minutes later it freezes.. Then i lose my wireless internet driver.. So i turn the computer off.. about 20 minutes later it works again for a little while then it freezes again... anyone know anything or have any suggestions.

Have you tried updating the driver for your air card?
Have you ran windows update? There may be a patch that will fix it.
Are you running a on wireless home network?
Do you have an antivirus program? May be a virus.

i haven't tried the aircard driver...thanx
