Hello all,

I have been mining Monero a little over a year. Ran great for several months. Several diff PCs with RX550s and RX560s. All cards have been one-click bios updated using Polaris. No other changes made to the cards BIOSes.

Lately XMR-Stak (any 2.10.x version) is either giving a video driver error (then that card stops working in XMR-stak), or it blue screens.

These are all Windows 7 Pro machines, running very stripped down.

I have tried numerous settings, both with the video card drivers, as well as intensity/work size/unroll settings.

I really could use some help here. I can provide any other needed info.
