Firstly you should not be using windows it cannot be trusted, use a Linux distributor with a vpn and Tor.
personaly I use a throw away USB drive wit tails, its much safe for the dark net. if the cops come I just remove the USB and nothings there for them to look at all ecrytped etc.
After your pc is secure enough and learn how to use Tor and tails and how to use bitcoins and how to transfer them etc....transfer smal amounts and learn how the system , there is so much if regarding this matter it's not funny here I'm just covering the basics on how to get there.
Also there are coin timbers so nothing can be traced back to u.
Tomfimrthe dalrmet markets google,Grams online link in Tor, on the left hand side there is a button to click active markets, aphabay seems my favourite.
Be carful,,,study more fire you begin the ire the study the safer u will stay. I'll add to this in the fire when I think about things but this should get u to the site atleast to look astound....also also use PGP if u dunno what it is learnt about it band how to use it or basically forgot about the darknet markets.
Hope I didn't confuse
