This first started happening when I upgraded from my old radeon 5450 HD gpu to my new GTX 750ti. I first thought it was a power issue but I have more than enough power to run every thing.
Computer specs
GPU: Geforce GTX 750ti
CPU: Intel quad core 2
Power supply: Corsair 500w
Motherboard: Rev A01
RAM: 4g ddrr2
my computer is a xps 420.
Here is a link to a video I made of this. Yes it is very crappy.
