okay, now sometimes at black parts of the screen there will be blue dots flickering around. but when i restart my monitor the problem goes away, and it seems the coloured boxes are only appearing with league of legends, tried bf3 and other more graphic intensive and there isn't such issues.
should i rma the card or is it the problem with my monitor? since i've used it for like 4-5 years while the gpu is new. thanks in advance.
