So for the past week or so my GPU would artifact anytime I boot down my system, but really only then. Gaming is fine, watching videos and managing files is completely stable and there are no issues. Any time I either restart or hard reboot though I get crazy checkerboard-like artifcating almost as if my GPU is on a bad overclock (had something similar happen to me on my other card and it was corrected by turning down my OC). Sometimes it happens on the login screen as well but that seems to be more at random.
It's an MSI Gaming X RX 480 4GB that's factory OC'd to 1303mhz and I just got it about a week and a half ago. No additional settings were touched before this happened. I've tried uping the power limit thinking maybe it wasn't getting enough to provide for the factory boost and even downclocking it to reference clock speeds, but to no avail. I'm a little wary about letting it continue on and seeing if it somehow corrects itself, I have about 2 weeks~ to get an exchange or a refund, but I'd rather not have to commute two cities over to bring it back to Microcenter. In the mean time, I'm running off my older GPU and it's been fine even with a moderate overclock.
Specs as of about a week ago:

I also have an EVGA 600w 80+ White Rated PSU. It's far from top tier but it hasn't given me any problems before on other cards.
I'm running on the 17.3.3 ReLive drivers, not sure if they're somehow conflicting with something else.
Would appreciate alternate opinions.
