there is a power supply tester available and a green light indicates it's fine
Clear your CMOS. I don't think the 9010 supports Sandy Bridge CPUs...and I'm not sure why you'd downgrade it like that? But, yeah, clear your CMOS with the original 3770 (i7, right?) in place, then try to boot it up again. But seriously, why would you try to go from a 3770 to a 2400?
