This first occoured playing minecraft yesterday, but it quickly resolved itself.. But the Entire UI flickered, and flashed and generally glitched. now it's spread to the entire system, while watching a video the entire interface corrupted, and its happening with alarming frequency. Currently it's turned off hoping that cooling down would help it. I guess minecraft is the cause, it pushes my system hard, thermally speaking, and i guess the GPU has finally taken heat damage. despite pushing fans high. Forgive the lack of comprehension, but this is a little serious, it's out of warranty and I'm unsure if I could pay for repairs, Let alone replace it.
