Garrys Mod 10 Is available on Steam, Which can be found at SteamPowered.com
You First need to get a Source Game, which can also be found on Steam, that is including Counter Strike: Source.
All and all it should cost about 21 US Dollars.
I suggest not trying to download it for free. there are many things like spyware and those things which could easily get onto your computer from a dodgy site. what im trying to say is that if you see garrys mod been sold for free, DONT take the offer. Its only a few pounds on the official steam site. Just buy it, OK?
If you have Garrys Mod, chances are it's already the latest version. (It auto updates)
Well you have to have steam to play garrys mod so tacticly you have to get steam first and than you can download garrys mod. :)
Gmod 9 is a free add on to Gary's Mod. This is available through your Steam client. Go to the Steam store and add it to your Steam client.

umm ok this doesnt make this much since, if your asking if gmod damages your computer, it depends on which gmod you have (if you got it free its gmod 9, if you got it for $10-13 its gmod 10/11). in gmod 9 there were LUA viruses, in gmod 10 there are fake addon viruses so you should just scan for viruses when you download addons (www.garrysmod.org). if you play online there are some players who find it enjoying to spam props and nukes until you crash. also if your computer is lower-end then some of the maps and addons can crash it. but OVERALL no, garrys mod does not damage your computer, some addons and players do. just be careful which addons you download. if your just playing gmod to build contraptions, probably no dammage there. OK now if your asking about some sort of computer in gmod (PCmod?) that damages players or something like that try www.facepunch.com/index.php
To download gmod for free, you must first find a website that offers the software for free. A simple search through the search engines should bring up quite a number of options for you to choose from.
It all depends on your internet connection speed. Mine took about an hour to download, while my friend's took four hours. Right before Gmod starts downloading, it will tell you how long it will take.
