FirePro m6100 and AMD Radeon HD 8950, GPU Error, GPU doesn't load and is not recognized

Hi , I have the issue for 6 months now and have been trying to solve it but I am not able to. I have Windows 10 installed on my Dell Precision M6800 Mobile Workstation Core i7, 4th Gen 4800MQ 2.7 GHz.

I was wondering if anybody have found a solution to the problem regarding the GPU Error Not Detected Automatically. I have tried uninstalling, reinstalling latest drivers both automatically (Windows 10 does it itself) and manually (I do myself from AMD website). But I couldn't find a solution.

I have the "Dell Support Assistant", it recommends, downloads and installs AMD FirePro m6100. But on "Windows Update" in settings, I see AMD Radeon HD 8950 to be installed. I am confused which one is it?

No matter which one of the two I have installed, the problem is; both of them switch off everytime I turn ON the system which is quite frustrating. I don't see the GPU in Device Manager.

When I plug the system in for charging, I have to restart it and get to BIOS using the F2 key. There I press the "Load Defaults" button in the lower right corner and then "Exit". The system restarts and the GPU sometimes gets detected. I can see it in device manager as longs as the system is ON. When I switch the system off and the next time I turn it ON, the system goes off for a second "possibly reverting to some other settings" and it gets turned ON. Then I open device manager, under the display adapter, the GPU doesn't show up.

I have tried my best but I didn't find any solution. If anybody can help, that would be appreciated 

Thanks, Asim.
