Remember, this is Not Financial Advice.
The easiest way is to use GPU (Computer Graphic Card) to do the mining.
However, since Sept 2022, mining has dropped in value because ETH moved from PoW to PoS.
I don't recommend buying ASIC unless you are a professional miner.
Next is beware that MINERS can be risky.
There can be "Keylogger" or Virus with some of this software.
Because of that, I can't recommend or suggest how to do this.
There are millions of YouTube Videos on how to mine using your Gaming PC's GPU.
