Since it's bluescreens on video playback this sounds like the old hardware acceleration issue. I can't quite figure out what video player you are using but VLC PLAYER does not use CODECs and the hardware acceleration setting varies with the player or web browser.
Since all this has long discussions I will shortchange you here. It is video driver related and on some machines was never fixed. Really irks folk that rediscover this area. I continue to disable video hardware acceleration and a few push to fix this and encounter sadness.
Hello,
Yesterday I noted that all my video players have only top left corner visible (rest was green), I installed K like codecs Mega version. From that time my laptop started to restart randomly or gave blue screens. Uninstalling the codecs did not help. First blue screen: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (dxgmm1.sys). I decided to back-up the system, but it did not change much. From time to time I get resets or blue screens (IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT_IN_NONPAGED_AREA) and idk what to do with this. I have made antivirus scans (MBAM, Avast, etc.) and they've found nothing.
