The title pretty much explains everything. I got the rx 470 MSI gaming x 4gb and installed it and it seems to work fine until after about 15 mins it either freezes or has a blue screen. When it freezes it will still play music in the background which leads me to believe the gpu is at fault here. I have reinstalled drivers multiple times.I have also tried the second pci slot. Any idea what could be wrong?
Specs:
CPU: FX 8350
GPU: RX 470 (before it was the r9 270)
