Recently ive got an used vega 64, but it has lots of problems, the most annoying one is that sometimes when i launch a game, an error message appears saying that ther is not enough memory to locate a texture, sometimes the message doesnt appear and the game just crashes, the other problem is that when the pc is in sleep mode the gpu fans randomly start spinning at 100%, and i have to force shut down my pc, i dont know if its a hardware problem or maybe it has been flashed, has anyone experienced a similar issue?
