I just re-installed Windows 10 completely. Formatted my whole HDD. Now the problem is my PC isn't recognizing any audio device. It isn't even recognizing blue-tooth and wireless. Now I have got myself a USB wireless adapter.
The main problem is about Audio.
I tried to install driver, then I saw there wasn't even a Sound,Audio and Game Controllers. So tried to solve that. There is found realtek. But it crashed during that coping or downloading screen. So I went to advanced mode and tried to add that. Now it went into BSOD, as there was no restoration point Windows couldn't start again. Well, I waited for a long. Then I restarted, still BSOD. I installed again. Now there is no audio driver and I can't even find realtek on the list.
I connected a speaker with intention that after plugging in devices drivers get installed, but no luck.
Here is snap of no realtek found and no Audio output is installed :
Device configuration :
