I have two pc at home . Both a roughly 5 to 6 yrs old. I have decided to buy another computer because the desktop (which I paid a fortune for at the time) just goes blue scree every tinme I use it; which is of course irritating. The othe i s a collegeg Toshiba lap top 256 Ram; so very slow and drove me insane. In your view what should I investin for home and professional use. Any comments welcome and appreciated
