My windows 8 is randomly logging off on its own, bug?

I have this problem also...  Windows will randomly log off and lock. I think it may be a graphics card driver error related to Adobe flash. I believe I have isolated an example on my local newspaper website, SFGATE.com (The San Francisco Chronicle) while using internet explorer. Google Chrome or Mozilla Firefox does not cause this problem, it has only been expearenced on Microsoft internet explorer 11. Also youtube can cause it some times but not so often, SFGATE will crash windows 90% of the time (while using iExplorer).

To recreate the crash use the following hardware and software setup

OS: Microsoft Windows 8.1 (did not ever happen on 8)

Hardware: Lenovo Thinkpad W510

GPU: Nvidia Quadro 880M

GPU Driver: 341.44 (I rolled this driver backwards and forwards and that did not make a difference.

Software: Microsoft internet explorer 11; Adobe Flash; SF chronicle sfgate.com

At the time of the crash I found this entry in the event viewer:

4:52 PM "initLock" NVWMI

I would investigate more, and try the myriad of recommended tweaking Vinod N @ Microsoft listed below, but I have a headache and need to redo the last 2 hours of work before I can eat tonight... I was almost done for the day too...

I'll try it... but do you think it can be this causing the random 'logoff'? I've not noticed any memory issues, and the times that these events ocurred was when I was just typing a text on texmaker. I'll also check this GDIView when I get back from work.

It can cause the random logoff, and is what causes it for me.

If you haven't already, increase your shared heap sizes, as outlined here.  Mine looks like: 

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,65536,2048 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

If like me, you've already done that and you still run up against the limits, the best you can do is to monitor your GDI handles with GDIView and try to stay under the limits. Browsers in particular use a lot of handles.

Oh, and search for "GDI", "resources", and "instability" in the Windows 10 feedback and vote up the ones related to system resources, so that maybe the powers that be at Microsoft will pay some attention.

My Windows 8 randomly kicks me to the password enter screen. All my programs stay up and I just have to type my password and hit enter to get back in. I am also not doing anything strenuous on the machine. The machine is overclocked though but seems stable - no blue screens.

I'm having exactly the same issue. Does anyone managed to solve this specific quoted case? I've bought a new PC and I am already experiencing this stuff, and I don't know if I should use my guarantee or if this is some not solved bug specific for my hardware.

By the way, my hardware is:

Intel i7 4790 3.60Ghz 4th Gen / 16GB DDR3 / SSHD 1TB / DVD-RW / MSI GTX 970 GAMING 4GB C/HDMI / Gab Phantom 240 White/ Fonte PCYes! 600W Series 80 PLUS Bronze

I am kinda desperate and don't know if I should change my OS to W7. Please, help me ):

Forgot to mention my MOBO: ASUS-Z97M-PLUS
