Let's start from beguining of problem. About 6 months ago my pc would crash but only when playing 2 games. League of ledgends, or fallout 4. I also played cs:go, star wars battlefront, Ark: survival evolved, NBA2K17, and GTA 5 and had no issues at all, or if i stream xfinity, or netflix nothing, only crash were the first 2 games i mentioned. so i replaced video card because i did ram test, 0 errors, hardrive test, 0 errors, replaced power supply still had same issue. My video card was a xfx R7 260x 2gb double d and one of the fans wasnt spinning anymore so i determined it was the video card. so i bought a xfx RX 460 4 gb double d and i had to install it in secondary slot running at 4x x16 2.0 because primary it would cover all my sata plugs. now my pc doesnt crash anymore but freezes and during anything at random times. help please? i stress test the video card and did fine. sorry for bad grammer and thank you for any help.
