Hi,
It's highly doubtful a graphics card would stop you logging in to a website. Check what applications and services you have running whilst online, using Task Manager, End Process of any you don't recognize or are wary of; and give your laptop a clear-out of temp and useless files and programs you don't use.
Update drivers, visit Windows Update, install Flash Player and Shockwave and see if you need Java for this gaming website.
