Hello, after a few minutes of gaming strange textures start to appear on my screen and sometimes blue lights too and the overall fps is really low. Im playing bfbc2, bf1 and lately PlayerUnknown's Battleground.

I5 2500 quad core
RX460 2gb ddr5
8gb 1333mhz ddr3
380w 80plus bronze psu
Res 1600x900

I sent the gpu to service but they sent it back saying that : defect not manifested. I tried different drivers too.

Any suggestions? Temps seem to be fine, 50c on cpu and 64c on gpu at full load when the textures are appearing.
What can i do? I was thinking i could sell the gpu as the service said it runs well. I could get a gtx 1050 ti 4gb
