Don't be ridicolous slimcloud. Noone can hack into your computer unless they know your computer's IP address (of the format X.X.X.X where each X is a value from 0 to 255). The IP address is how other computers find your computer when sending stuff accross the web, such as web pages. Each computer has its own individual IP. For most home computers IP is assigned dynamically when you connect to the internet (ie, it is not the same every time you connect to the internet).

Telling someone your computer details is 100% safe unless you also tell them your IP address. If you still don't know what the hell an IP address is then you're basically safe because there is no way you can accidentally give it out if you don't know what it is (it takes specific knowledge to even find out your IP, it's not something you can do by accident).
