I very recently bought a new GTX 780, and installed it into my PC. I was previously running an HD 7750, with a phenom II x4 965, 8GB RAM and a 650w PSU. However, after installing it, my PSU made a loud whirring/crackling sound, accompanied with a slight whiff of burning plastic. I also noticed that in some games, there were flickering distorted lines across the screen. Since then, I've upgraded my (very old) PSU for a new 750w version.
However, now everything is working normally, except my screen is ever so slightly blurry. It's not obvious at a first glance, but after a few seconds it becomes clear that the image isn't as sharp as before, and causes slight headaches. I have installed the latest Nvidia drivers, and I want to say I'm sure I didn't notice this before (but I can't guarantee this). My GTX 780 is a direct MSI manufacturer refurbished model from ebuyer, otherwise unbranded. Any advice?
