Occasional black screen/hang which doesn't produce minidumps
Recently i've updated my pc to Windows 10 and now it keeps crashing/hanging quite often and mostly while im in games.
Basically the "shutdown sound" plays, PC freezes, monitor goes black, keyboard and everything else switches off but apparently the pc continues working since i could hear teamspeak in the background once. Nothing else works and the only thing i can do is hard reboot. Unfortunately because of that no minidump is created and nothing is mentioned in windows event journal (except unexpected shutdown). Its almost as if PC switches off videocard and monitor and all peripherals but doesn't reboot.
I've run several hdd tests (crystal disk info, hdd tune pro, acronis disk doctor, western digital hdd tool) and 2 of those (crystal disk and hdd tune pro) showed 1 bad sector in a non system drive while the other two showed healthy/fine disks. My system is on ssd drive which is healthy according to all 4 tests.
I've also tested RAM on memtest86 and it did not found any errors in one full pass though i realise that it might take several passes to show errors. I've also run driver verifier and checked all non system drivers but again did not get any issues.
Additionally i've encountered some other issues after updating to Windows 10 which might or might not be related to the issue above:
1) Videos in media players as well as in flash/youtube sometimes stutter. This never happened before and it seems to be related to higher CPU or disk usage, even though previously videos did not stutter even under load.
2) Some software like lcdhost, logitech gaming software, aida64 behaves strangely - sometimes applications hang, sometimes they do not load, sometimes they unload. I've actually had one BSOD related to AIDA64 which produced minidump but it seems to have been fixed with the beta release.
3)Windows event journal mentions some issues with winnit and service control manager/_session1.
4)Nvidiabackend process keeps taking up to 40% of CPU power occasionally. Before updating to windows 10 i've never had that issue. Killing the process results in "nvidia geforce experience" not loading and then the process restarts anyway.
Im not sure what to do next since i've checked and tested just about anything.
