Are you able to boot in safe mode for win 7?

if so run msconfig > Boot tab > Advanced options > set Number of processors to 2.

if that doesn't work set Number of processors to 1 and boot as normal to update the Chipset Software and any hardware updates by windows that might let you run 2 processors.

That was great!! I removed the chip ran windows 7 and changed the configuration in msconfig for 2 processors. Restarted with the new chip and VOILA!
