Allow default driver when not using nVidia gCard

[DiGenius]

Hi, I'm relatively new to the X-Display part of Linux. I boot Linux Mint 13- Mate from my external HDD. This use to boot fine without display problems until I installed version 304.64 nVidia Driver to run my Desktop's GeForce 6150SE (Using this site http://www.upubuntu.com/2012/11/install-nvidia-driver-30464-in-ubuntu.html). Now, when I try to boot on any other system, I get a really small resolution. It's obvious that that's because they don't have the same gCard as my Desktop, but there must be a way to switch to the default driver in this case. I just need some help on how to do it without removing the nVidia Driver. Thanks in advance.
