Graphics card freaked out on me? https://www.youtube.com/watch?v=ENHPU9xm_wg

So i built a computer a few months ago and its had a few problems that nobody on here could solve, such as one time it froze completely and i had to manually restart it, and some other stuff.

Anyways:

Sometime when im in a game of league the screen will randomly flash white, for a frame, and at first i thought i was just blinking or something but no. also: this only happens when i play league.

So i was just in a league game and my whole screen started freaking the fuck out, i tried alt tabbing but my desktop was doing it too...i got a vid of it if anyone is curious:

Could be your memory. Test it by taking one stick out. If the flashing still happens, swap it with the other stick (the one you took out).

Well..there are many reasons for bad ram. If you got this problem right from the start when you built your PC you should return it and ask for a new one. But if it worked fine for a while then got bad, it could be heat, dust, power surge...and a load of other things.
