Graphical Error help

[Antisi]

Hej,

I'm just going to throw this out there and see if anyone has any suggestions.

lately I've been experiencing a weird graphical bug while playing a game ( league of legends) it starts off fine but after a while i start seeing red and blue sketchy squares going diagonally across the screen, these generally dissapear once ive moved a window or animation across them and are mostly visible on pure black/ white backdrops, the squares also carry on once
I've quit the game.

I'm running a GTX 275 and I've tried updating the drivers etc


any help is appreciated.

That sounds like borderline overheating of your graphic card.
I had a GeForce 8600M GT in my laptop that had strange graphic glitches and it eventually stopped working altogether. Thankfully the GPU can be swapped out and replaced easily with my laptop so it was a £48 fix.

I'd see about improving your GPU cooling.
