Windows 10: Windows Errors After Installing New RAM and SSD

After I installing my RAM, some errors occured leading to some BSOD. After I adjusted it until it worked, some windows system file might corrupt. Some errors are :- No audio device is installed eventhough I can see it on devices menu.- Microsoft Store cannot be opened- Spotify, NVIDIA Experience, Teams, and might be more applications is appeared to be offline when it is cleary that my PC is connected to the internet.On services, Windows Audio status is Stopped. I tried to Start it but Error 0x80070005 occured. Starting it from task manager also is not possible.

Issues with installation of new MSATA SSD

Yes it was a clean install on a new SSD. The laptop boots into windows fine. As mentioned in the earlier posts I'm trying to get the BIOS to see the new SSD as UEFI and not Legacy as it originally did when I installed the SSD and installed windows. I changed it from MBR to GPT from the windows installation screen and have since followed the steps above to allocate the drive an EFI partition, the drive itself still isn't seen under UEFI boot options in the BIOS itself though and I'd imagine it may be the final steps listed that may resolve this but for it doesn't want to allow it. I'm happy to post pictures, could you be a bit more specific as to what you'd like me to post. Thanks Daniel

 

Error when installing Win7

when Installing Windows 7 I get an error saying ""A required CD/DVD drive device driver is missing. If you have a floppy disk, CD, DVD, or USB flash drive, please insert it now. Note: If the windows installation media is in the CD/DVD drive, you can safely remove it for this step." What should I do to get Windows to install?
