I ordered a new Corsair PSU having been told my old Seasonic was junk, it made no difference. After 9 straight hours of effort no change, PC wouldn't boot, no video signal. In the end I was no longer able to boot my system even with the Nvidia card. After more hours and hours of T/S I was told by MSI support that the MB was toast and needed RMA. The support rep insisted the RX580 was NOT the cause of any of this drama.I couldn't wait for 6-8 weeks to get another MB from MSI so I forked out $100's of dollars for my parts which you see above. It worked. Played for hours at highest settings. Meanwhile....I had decided to try out an SSD with my new build. I installed WIN10 but chose PRO instead of HOME so my activation would not work. I decided to go ahead and reinstall WIN10 HOME. Around 2 am the reinstall finished. All drivers updated. Back where I was before when it worked fine. Fired up XCOM 1 LW. Started mission, 10 minutes later....BZZZZZZZZZZZZZ...BLUE SCREEN......CRASH.I don't know what else to try except get rid of the card. The last thing I found to try was MSI Afterburner. I was told you can go in there and UNDERclock the card thus making it more stable. Others said RAISE some settings would fix it. I cannot seem to find a guide to UNDERCLOCK the RX580 and make it more stable (not crash). I have only tested it on XCOM 1 due to time limitations but that should not make a difference. I played XCOM with my Nvidia 2GB for over a year with never an issue, just lower graphics settings.
