Basically, Dell doesn't work that way..If you're going to replace the motherboard with a different type, as well as other items like graphics cards, etc., then you won't be able to use the Dell installed operating system and hardware.. Simply swapping in the old hard drive generally doesn't function. The factory installation will be looking for the "old" hardware drivers and thus won't function correctly.. In addition, if you try to wipe the current hard drive or install a different hard drive, then the Recovery discs won't install or validate correctly either..
So... if you're looking to replace the motherboard, I would look for all new parts or a new computer entirely.
Hope this helps.
is ther a place to find replacement parts for this dell model. i would like to replace the motherboard to the newer tech. i.e. SATA ,IDE CONTROLLORS MAYBE ONE WITH AGP AND E EXPRESS ECT.
