I have a Foxconn Blackops board socket 775 that runs a Q6600 like a champ. I got a Q9550 to give it a boost but the board will not boot. The CPU is supported with the current BIOS revisions I have installed: http://www.foxconnsupport.com/cpusu...ocket=Socket 775&model=BLACKOPS&cputype=Intel I have cleared CMOS multiple times and even removed the CMOS battery for good measure. What happens is the board receives power and the fans turn,etc but no beep or video signal. It just sits there sometimes. Other times it is cycling on and off every 2-3 seconds.
