I honestly don't know how it happened.
Last weekend I went home to work (at college), and I came back, and noticed some very minor artifacting that remebled dead pixels almosts (except they would go away when I move the application around). It progressively got worse, until it just randomly...
I'm having a very bad problem. Not sure if it's the GPU or PSU dying.
Here are some screenshots:

It also looks all messed...
