I've built my computer and run fairly decent products in it but for some reason the on board graphics as well as the graphics card I installed both show up pixely almost as if everything is in 240p. I am curious if I'm tapping out my power supply or if it's another cause...?
i7 processor
GeForce 960 graphics card
8gb ram 2x4
500 w power supply

running on a led flat screen monitor, I've had it hooked up to other computers and haven't had any issues with resolution.
