I have seen you guys on here talking about the processor speeds, types of mother boards, memory and such. My brother built my computer, and I know a little bit about what is in it. But how do I find out what type of mother board, processors (I'm pretty sure I have dual intel processors), and other stuff that I have in my computer?

Thanks,

Leon

Without cracking the case, you can download and run the Belarc Advisor. It tells you pretty much everything. And it's free.

you can right click on my computer and select properties, it'll tell you if you have dual processors and what speeds too
