I'll repeat the story again as by back up I meant restore Sry English is my second lang (u probably saw some polish words in the zip file).
Few days ago 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 do system restore, 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 - all of these only once) and idk what to do with this. I have made antivirus scans (MBAM, Avast, etc.) and they've found nothing.
UPDATE: I don't get blue screens any more. The laptop restarts ONLY after long break from being turned off (but still plugged in to power supply) shortly after the desktop shows up (Kernel-power id 41 category 63). It does not happen when I turn it off manually and on. I did it 3 times and no reset. So today to see if it's problem with power (electricity), after typing my password to log in I plugged in my battery and MY PC GOT BLUE SCREEN instantly (SYSTEM_SERVICE_EXCEPTION). So now I am thinking it is related to power or power supply.
