Got an AMD RX 6750XT about a month ago, and I can't seem to launch games without getting poor frames or stuttering without having to restart my PC. This resolves it like 6/10 times. Sometimes my screen will go black and I have to sit there for a couple minutes before it comes back. I've tried out both drivers available for it, doing clean wipes with the AMD utility cleanup in between, neither driver really seems to make a difference. I'm thinking it could be due to a low psu (mine is only 650W), but my brother got has the same gpu and an almost identical pc build and hasn't had any of these issues. Any thoughts are appreciated.
PSU = 650W
CPU = AMD Ryzen 7 3700X (8 core)
Motherboard = TUF Gaming B550M-Plus
