Ok, so I went ahead and did the system restore and the laptop is now working. But it's much slower and it feels hotter and it makes more noise than it did before. Does this mean the fan is broken?
I see everyone is underlining how stupid it was of me to mine on this laptop. I agree, I just didn't do my homework beforehand and I won't be mining again.
Biggest question is it still under warranty? If it is I would send it back and get it fixed.
If it's out of warranty you have a battle on your hand. Laptops are not really made for you to change out things like a desktop. They might give you access to RAM if lucky but a lot of it is off limits and hard to get to. And void warranty possibly by opening it.
