This sounds similar to the crash I had earlier. Played several Dom matches just fine. Then I go into a Conquest match and mid game, my PC shuts off and restarts out of nowhere. When I check event viewer, it didn't tell me much, so I checked the crash dump files. Once I put them into a Windows Debugger to make it readable, the main issue did mention easyanticheat.sys and it was the same time it happened. So something has to be going on with EAC. Did you have Secure Boot enabled at the time? I only ask because apparently, my PC had it enabled in bios but it wasn't "active", so it showed up as not being on in system info. If that's the case, I shouldn't have been able to even play the beta at all for the hour and a half that I did before the crash.
