In XP or lower systems, it is fairly easy to find this information. Just either right-click on the My Computer icon on your desktop, choose Properties, and the info is on the General tab. Or you can go Start>Control Panel>System to find the System Properties.
Then you can put it in your signature, or just type it in with your question, something like this:
Code: Select all
[color=#BF0000]computer brand and type (desktop / laptop) Operating system other operating system if dual boot processor MB or GB of RAM([/color])
And, if you use only one browser (i. e. Internet Explorer, Firefox, Opera, etc.) it may help to add that to the information.
