Well.. the motherboard has a second rev that supports core 2 duo and I own ofc the first one. That explains the refusing to boot .
The 5-second shut down was because the heat sink was not properly touching the CPU cause of 2 corners of the metallic thing that holds the CPU still. I did 2 channels on it and now fits ok and the problem is gone.
Thanks for the help.
Hi. I have a big problem...
I have P5LD2-VM , with an old Celeron single core 2.8ghz .
I just bought a new CPU . Core 2 duo e6600 and an alpine 11 rev 2 cooler. I installed the new cpu and the cooler but the pc won't boot . There is no display on screen . I tried removing and repluging everything but same result... I reinstalled old cpu with the new cooler and it boots ok ... I updated the bios to the lasted version ... And I'm sure the motherboard supports the CPU.
So what could it be? Did I installed the cooler wrong ? Is it maybe not tight enough ? May the mb died?
P.S : With the old CPU the pc shuts down after 5 seconds but boots normaly.
