Recently, my computer ran into some problems, mostly concerning the GPU or its driver. I have an Aftershock S-15 (Clevo P650RS on the sticker) notebook with i7-6700HQ, GTX1070 for gaming. Additional specs:
I had several blue screens before so I continually monitor the Event Viewer for new things.
Now, when starting my computer from cold boot (such as, about 6 hours turned off), first the BIOS/manufacturer logo screen shows, then the screen turns off. After a noticeable amount of time (~10 seconds), the BIOS screen turns on again and proceeds into Windows.
On checking the Event Viewer, a kernel-power event is logged, SYSTEM_SERVICE_EXCEPTION, probably caused by nvlddmkm.sys (WhoCrashed). Note that in the boot-up, I do not see a blue screen.
Sometimes, the notebook will boot completely fine, but in this case the Device Manager shows that the Nvidia GPU is disabled ("Windows has stopped this device because it has reported problems"). When I play games in this state, the notebook only uses the integrated GPU. Restarting the PC at this point always causes the GPU to become normal again.
When I update the driver, the computer BSODs during gaming (VIDEO_TDR_FAILURE). This happens regularly and predictably. Rolling back the driver causes the blue screens to stop.
Using the old driver, I can play demanding games reliably without errors or crashes. (I used DDU to uninstall the driver). I am also able to use the pc like before. However, I am concerned that the system will deteriorate further unless something is done. Recently, the "hidden" blue screens happen more frequently, and sometimes the BIOS restarts triggers the drive error-check before going to Windows.
Now, if I restart the notebook, or if shut it down and boot it up again within a short time, the "hidden BSOD" does not happen, and no kernel-power events are logged.
I am currently backing up my files for a full system reformat+reinstall OS.
I would really appreciate your help on this one.
