I got this old ECS G41-M7 v1.0 board with a C2D E6750 in. It works mostly fine despite it's age. Also has 2x1 GB DDR3 1333 @ 1066 MHz memory (2x4 GB tested later).
I also have a Q6600, which the board allegedly supports and tried to put that into the board. So I did and for several hours it did with no trouble other than the components close to the socket gaining plenty of heat (ir does it even with the C2D so wansn't big deal). Before putting the Q6600, I decided to update BIOS to the lastest version.
After testing the C2Q, I've returned the E6750 back to place. A few days later I decided tomar put back the Q6600 and the system wont POST, just turns on with no video output nor any noticeable boot activity. Does work with the C2D to this date.
Different memory, PSUs, dGPU, CMOS flush, BIOS reflash have been tested with no effect.
Q6600 did work on another board to tell if the CPU did go bad. It didn't thankfuly.
Is there any explanation to this behavior?, Is ir possible to fix this thing?.
