Yes - I made a post here last night in which I appear to have fixed the Black Screen / Rebooting issue (although I need to test more) by introducing a more powerful Power Supply Unit directly to my graphics card. Please see this post here: 10 Reasons AoE2:DE is so bad
Whatever changed in DE it appears to be maxing out my 600w PSU on a GTX1080 (I never had a problem until now…)
