Hi Mark, and thanks again for all your help with this. What you mention above sounds very technical for me and I am very anxious about trying a fresh install now.
This is my laptop, which I purchased on December 29th 2018:
Medion Erazer P7651 Core i7-8550U 8GB 1TB & 128GB GeForce GTX 1050 17.3 Inch Windows 10 Gaming Laptop
I don't know what you mean by "the issuing devices". The webcam, USB3 and one of the USB2s are not working I don't know the brand of those or what drivers they were using.
As I purchased new last December, it did not have a previous OS that I can see.
Thanks again.
Regards
Tommy
