System failed CPU test

I have a P5AD2-E Deluxe motherboard with a Intel P4 775 3GHz processor, both were bought in September 2005.

During the last week, when I switch on the desktop PC I can heard the error sound: "System failed CPU test" and the computer doesn't boot. I have tried to:
_ re-seated the processor
_ reset BIOS
_ check the PSU in other system
_ boot the system with the MB, processor and PSU

, but the error is not still fixed. I have read something about problems with a solder of the heatsink in older MB but I am not sure this is the case.

Could you tell me have can I solve this problem?
