It could be the "adapter default" refresh rate is going over 60Hz.  I
suggest you force 60Hz or lower refresh (assuming the drivers allow).  Other
considerations would be BIOS settings (power mgmt. settings, AGP vs. PCI for
newer mobo, et. al.).  Make sure all cards are fully contacting / inserted
also.
