Moreover all work ok if i do not perform comaction (except video card device has error 12 (code 12)). OS: Windows 7 64bit Everyting i can collect (only before compaction) in attachment diag.zip Help please.. Thanks to Nando: The solution was: 0. Remove all drivers 1. Override DSDT http://forum.techinferno.com/diy-e-gpu-projects/3539-guide-dsdt-override-simultaneous-igpu-dgpu-egpu.html 2. Select 56. 25Gb-bit enpoint 3. Run compaction. Select iGPU+eGPU compaction 4. Force 32 bit for iGPU 5. Install drivers and it should be ok
