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
