Every Steam game is throwing error

[TheMiniMiney]

I did a fresh installation on my laptop , installed the drivers required and installed steam . Then i added my internal HDD back to my laptop and added the steam library to steam. Now almost every game is throwing errors. I made sure the drive had read/write permissions. 
Cuphead is starting and plays the menu music , but no visuals. ( for what ever reason forcing it to DirectX12 is working , but i want it to start normally like before)
Spyro reignited trilogy started at first , but now throws "The UE4-Falcon Game has crashed and will close
            LolLevelFatalError
            [File:D:\Bamboo\buildbot-package\Engine\Source\Runtime\D3D12RHI\Private\D3D12Util.cpp] [Line: 242]
            (Device-> "TPSOFunctionMap<TDesc>::GetCreatePipelineState()((Desc,IID_PPV_ARGS(&PSO)) failed
            at
            D:\Bamboo\buildbot-package\Engine\Source\Runtime\D3D12RHI\Private\Windows\WindowsD3D12PipelineState.cpp:601 with error E_INVALIDARG" error
CS 1.6 also starts with a blank screen. Before it gave an error loading library error.

WMR Portal gives outdated driver issue , whereas i have the latest drivers and i had used wmr headset on this before.

 

I can't understand whats wrong here. I installed the latest Intel drivers and Nvidia drivers (ver. 451.67) from Geforce Experience.

has the drive name or location changed when you added the drive back in it might be trying to locate files that could have been in a C drive when your originally installed them but is now in a different drive?

so I downloaded DirectX runtime installer which included 9/10/11 and somehow that fixed it . I will test out some more games and update whether the problems persists or not. But thanks alot for your time.
