Hi!
I have simillar problem. When I've chainloaded my win7 i saw CODE 43. It can be fixed by removing my eGPU from devices manager and "scanning for hardware changes" but when i reboot i have two "working" GPUs in devices manager (my dGPU and eGPU is working, i don't have iGPU) but system cant detect external monitor which is plugged to my eGPU. I can remove eGPU again and do this process again but after few replays i can't remove eGPU - device manager is hanging and i have to reboot in repair mode to remove all the GPUs and use DDU to remove drivers. Then reboot to normal mode win7 and detect the GPUs again, install drivers, and need to replay all the proces that i wrote higher.
My specification:
Lenovo g560
- i5 460m
- 8 GB ram
- V8.0 EXP GDC Beast (expresscard version)
- dGPU is nVidia GeForce 310m
- eGPU is nVidia GeForce 9800GT (it is cheap and really OP - the best for tests before i will buy new graphics card )
- iGPU doesn't egsist in my laptop (it is included to i5 but blocked by MoBo :< )
- win7 Professional 64bit
Please help guys. I'm trying to resolve this problem about 1.5 week with short breaks and it's killing me :/
And... Sry for bad english. I hope that you'll understand me
