Onboard stuff isn't... But I'm not sure what else would be the problem unless you have some odd resource conflicts.
It shouldn't be hard to get another card, if it is dying. Just disable it and install the new one.
*rant* This is why I hate all the onboard stuff things have anymore! This is a laptop, right? Well desktops have the same problems, and when something dies or you upgrade, you're still stuck with the old one
