Why can't my 64 bit laptop process 64 bit Windows 10?

[Draigo Rhyddid]

No matter what I try or do, my 64 bit laptop (yes it is definitely 64 bit) won't run on 64 bit Windows 10. It says it can't run on my PC, but 32 bit works? If anyone can find me a solution to this problem, I'd be forever grateful, because no one else seems to be having this problem. Thanks

What make/model is your laptop?
