I downloaded Ubuntu 16.04 yesterday and I love it...unfortunately the screen flickers when I open anything or even move the mouse at times. Is this a problem with my computer or Ubuntu?

Ctrl+Alt+T to open Terminal. If you hold your (I assume you use a dual-boot with Windows) Windows button between Ctrl/fn and Alt, you can see every command for Ubuntu. You have to write it in Terminal I think, works like cmd of Windows.
If your video card driver showing Gallium 0.4 on NVCA then it means that you have the open source NVidia drivers installed. It would be worth trying the proprietary version from NVidia.
You mentioned in comments that the result from the command lspci|grep in a terminal was
NVIDIA Corporation C77 [GeForce 8200M G]
If you installed an x64 version of linux, you can try downloading and installing this driver:

Your card is not on the list of the "supported products", but when you navigate through the filters of the website that's the one that shows up as result.
