Hello.

I have been looking into and reading about cryptocurrencies for a few weeks now and decided to "give it a whirl". At the moment I have only dabbled in faucets (I understand that this is not "profitable", even "pointless" some might say, but nevertheless) and have earned my first couple cryptos (LTC and DGE so far). I have also looked into the mining part and from what I understand, using a laptop (as I don't own a PC myself) to mine would be suicidal due to overheating.
 
Basicly, what I want to know is - how hard is it to install a miner on a PC (as i have never done that before) and would it be possible to configure a miner to use low amounts of resources? I am thinking maybe to install a miner in my PC at work but would configure it so it would not critically halt my work, if that is possible.
