First off:

I'M A TOTAL NOOB, when it comes to mining.

So I have a gaming PC which I'm trying to mine on.

CPU: Ryzen 3900x
GPU: RTX 2070 super

Have been mining on Nicehash and was pleased in the beginning. Now i'm just getting half of the hashrate I have 2 weeks before (not accounting for the latest price drop), it's the amount of satoshi which have dropped 50%!

Would like to mine with claymore now and earn some ETH, but don't find the guide easy for a noob to follow. Could anyone send a link or direct me to a more noob friendly guide or youtube video? Have tried on youtube but the steps are quit different since they are 1 year old...

Does anyone know a good guide I can follow to setup my gaming pc to run on claymore?

PS: Don't tell me it's not profitable because you don't know the electricity rate i'm paying. So please leave that out, I want to mine for whatever reason and it's not just profit driven.
