Today I installed a new graphics card in my computer, I followed the directions correctly by uninstalling the old graphics card and installing the new one, but in the process 3 drivers were lost. I cant connect to the internet now and I have no Idea what to do. Any suggestions?

Try to revert to the most recent restore point before you started all that and put the old card back for now to make sure that there are no driver conflicts. If that doesn't work you will have to download the computer's chipset drivers from the manufacturer's website. Without knowing more about your computer I can't tell you where they are. If you need more help than this we will need to know more information--namely the computer's make/model and operating system.
