hi guys, i want to swap the motherboard in my dell 9150 to one whic hcan definately hold a core 2 duo conroe, when i do this, would i have to format my HD, or reinstall windows or would everything be normal and smooth sailing with the mobo swap, and would it just be an issue with installing drivers for the mobo, pls help i would like to know what to expect, my current mobo, no one is too sure it would work with a core 2 duo even tho it has a pentium d so a mobo swap sounded like the best solution.
