How can i find out what kind of ram and motherboard i have without opening my computer?
Download and install CPU Z
Or check out here: http://www.motherboards.org/ with the help of the BIOS-string that shows at startup, bottom left on your screen
...or use THIS
You could also download SiSoftSandra Lite. It will tell you what you want to know about your motherboard and ram, without having to open your computer up.
