I know the recommendation is to reinstall Windows when you change mobos and processors, but I have always gotten away with carrying over the old Windows installation by just updating the drivers for the new hardware. Looks like I didn't get away with it this time. I went from an nvidia/AMD board to an Intel/Intel board with an E6750 , and now Windows is only seeing one core. CPU-Z shows the proper info, but Windows Device Manager only sees one processor, as does SiSoft Sandra. Benchmarks in Sandra and 3DMark06 are miserable.

I really, really don't want to reinstall XP, because I have a ton of programs that will have to be reinstalled. Is there any way to get XP to recognize the new processor?
 
Try updating the HAL on windows device manager, from whatever is set to ACPI Multiprocessor System and see if that does the trick

Hope it helps
 
w00t! It's fixed. Playing off of OldMX's suggestion, I figured I needed to cause a re-install of the ACPI configuration, so I rolled back the chip-set drivers then re-installed the latest chip-set drivers and updated the ACPI driver in Device Manager. Booyaa! Two processors showing. 3DMark06 went from 8729 to 11862!! Sandra benchies are right where they should be.

Thanks for the help, OldMX.
