I am not 100% that this is a graphics card issue but it's my only guess so far.
Basically I left my computer on for 8 hours and came back to strange squares floating around on websites and other applications. If I hovered over some hyperlinks the squares would move around and such.
Caught an example at the top of this page:
When I swapped tabs back and fourth they disappeared.
Specs:
Windows 7 64-bit
i5-2500 CPU @ 3.30GHz, 3301 Mhz 4 Cores

NVIDIA GeForce GTX 970
