If I change motherboards (and processors) from a Pentium to an Athalon, will there be any problems with my Installation of Windows XP? I don't want to reinstall. I have been told there could be some HAL (hardware abstraction layer) issues with such a drastic hardware change (pentium-athalon) and I would have to reinstall XP, not to mention my programs and such. Is there any way I can change my mobo without reinstalling any software or OS? By the way, I will be switching out my P3 550mhz mobo (i don't know mobo) to an Albatron KX400-8X motherboard combined w/ an Athalon XP 2000+ CPU. Also, I checked under device manager and it says my current HAL is ACPI (currently running P3 550). Thanks.
