We will try to find ddr2 1066.
But what is happened, why not start now with old cpu?
No bip when start, (with memory or not)
Is posible, was maded something wrong, while prepared the socket....
Ok, thanks.
Is the neighbor's pc.
I suggest to check, all components on another pc.
Then try to start with video card in each slot and one stick memory in each slot, (all combination).
Also to use a magnifier to look the socket pins.
