im leaving work in 10 minutes so there might be a delay in my responses
Once you have the IP.
Switch PC Off and reinstall GPU. Switch it back on but do not plug any display ports in at all. iGPU and GPU should have no display cables connected into them.
Now switch your laptop on.
Gonna be difficult to take you through the whole way can anyone here take him through remote desktop to his pc and re-flashing the GPU bios ?
if not i will be home in around 1 hour and will take you through the rest of the steps.
