I've just bought a Intel Core 2 Duo Q9550 45nm. I've placed it on my motherboard GIGABYTE G31M-ES2L (checked to support the processor). BIOS updated to the last, but the pc can't load the OS : it freezes at memory test, for exemple...
Can you help me ?
Actually, regarding this, it is quite difficult to troubleshoot as you are using a Gigabyte board.
Try the cpu on another compatible board to make that the cpu is working fine. Possibly, it can be down to the motherboard or memory issue.
Apologies for the delay.
All the best,
