can u know the chipset or mother board model of intel without opening the c.p.u

Yes you can get your Motherboard model while you turning on your pc . It shows when you turn on your computer, just check yourself now.

normally computers ship with its driver CD, check whether you have them and identify the model from it. There are some system id utilities, by intel and other third parties, I am not sure whether they give exact model or not. Many people just go for formating, I don't do that, if you got any problems try to rectify rather than formating. Peace.

yes you can just simply download this software which is free http://www.belarc.com/free_download.html then it will give the detailed information for each and every device one more advantage,it also tells the driver information whether it is uptodate or outofdate thats it,enjoy
