It's allmost impossible to mine with your PC. You'll make a negative profit when mining with your CPU or GPU (you'll basically use more power than produce BTC + you'll burn your cpu pretty fast).
If you're serious about mining, you'll need to buy an ASIC, basically an antminer S7, antminer S9 or avalon 6 CAN be profitable IF your power is cheap enough AND your total cost is low enough (the cost to purchase the ASIC? PSU, cables, racks, cooling,...).
Step 1: calculate the purchasing costs
- look for second hand and new asics on this forum, the vendor's site, ...
- custom charges (they add a lot of tax in some countries)
- PSU, cabling, shelfs, fans,... It'll be loud, create a lot of heat and draw an big ammount of power
Step 2: see how much you pay for electricity
Step 3: enter everything here :

Divide the block reward (12,5 instead of 25), add 10% to the diff, and deduce the price with $50 (the block reward will halve in a couple of weeks, the diff and price adjustments are just to cover your bases, so you have less chances of burning yourself)
Step 4: see how long it'll take to just pay back your investment (if ever) and conclude it's not worth it

You might want to look into altcoin mining... Some of them can be mined with a decent GPU and can be traded for
BTC on an exchange
