Athlon 64 X2 DualCore 4400 for Esprimo E5600

Before some days I have purchased Athlon 64 X2 DualCore 4400 for Esprimo E5600. I have then swapped the CPU and booted it. But the error was encountered. First I booted with the Windows & 64 bit than with 32 bit but both time I encountered the same message i.e ‘Hardware Malfuntioning’. Then I tried installing the windows XP and it worked fine. Can any one of you figure out what was the cause of it ?
