I have found the culptit that caused BSOD on my system, a bit silly...

Even I checked "clean instal" the installer failed to overwrite this currently intalled files (locked by system):
13.09.2015 23:41 3495808 NV4_DISP.DLL
14.09.2015 00:41 3024384 NVAPI.DLL
14.09.2015 00:08 1049904 nvdispco3235598.dll
14.09.2015 00:18 912688 nvdispgenco3235598.dll
13.09.2015 23:41 73728 OpenCL.dll

And mixing old NV4_DISP.DLL with new NV4_MINI.SYS caused some IOCTL call memory corruption. (this is why reverting old NV4_MINI.SYS fixed this). I found it by trying to install some older WinXP backup made when I had GTX 670 - in that case all driver files was replaced by installer correctly and driver worked after reboot. By comparing files I found that my current version had few older driver files so I updated them manually (offline) and now it works fine. Next step I'll try on Dell 4k monitor at work...

You know the drill.
Safe mode, DDU.

I have multiboot so no problem to manipulate XP files offline but it just didn't come to my mind that not all files was copied and didn't checked them. Blindly hoping that clean install do what one would expect will do 😀
