There's more than just the title suggests and I'm at a loss here.

I've been running an MSI RX 5700 XT on my B450 Tomahawk for roughly the last month without issue. Today, the GPU started crashing the computer entirely...all screens go black, no crash message is recorded (no dump files appear at all). On a power down then reboot, the VGA Debug light stays up, no POST. I've been able to reboot with successful POST but it will operate for anywhere between 10 minutes and 2 hours before the computer will crash out again in the same manner.

I do not overclock any component. This pairing has been working quite well for the past month...then, all this.

Full specs are in the signature block.

Any ideas?

Thank you all in advance.

Never mind all...ended up being a bad GPU, unfortunately. Disappointing since the thing is only around a month old. Older RX 580 is back in and computer is functioning normally.
