I am not sure why you think you have AOL. Does your internet explorer perhaps have a branding across the top like "Internet Explorer provided by AOL"?

If you truly have AOL, you can remove it through the add/remove process like any other program. AOL hangs on like grim death and goes licking and screaming, but you can take it off like anything else.

As far as the sound card, shut down, pull the card and reboot. That will see the ESCD (extended system configuration data) update to see the card as gone. Then shut down again, put the card back in, and reboot. Windows should auto detect the new hardware and look for drivers. If you have a CD with drivers, install them first and THEN shut down and put the card in. And make sure when you are inside the case you unplug the power cable and touch the outside frame to discharge any static buildup in your body.

If that still fails, boot in safe mode once and let Windows fix what it sees to be wrong.

I don't know your level of experience and no offense intended but you don't sound all that experienced if you can't get AOL off your computer. You have a lot of knowledge here to draw from and we will help you all we can.
