Before I was going to upgrade my mobo and cpu,I decided to wait awhile,now that intel core2duo are so cheap,I'm am going to.Someone had posted a link where it showed how to install drivers for new mobo and whatever else was needed ,before powering down and swapping mobo and cpu,That way I can still use my HD and my copy of windows xp pro that I have,I have a dell with 630 cpu and 925xmobo,and sata hard drive,I just want to swap cpu and mobo without clean install as I have some stock utility that was dl,when I had a large sum of money in a stock acct.I dont have enough to get it now,and it doest let you copy it as it dls straight from website and installs.I really dont want to lose it just now,any ideas I do video encoding and I cant even sleep as long as it takes my 630 to encode 4 g,then burn it to dvd.THanks in advance>Marvin
