Asus P5G41C-M LX Unable to start after shutdown

[Whr]

Motherboard: Asus P5G41C-M LX
CPU: Xeon X5450
RAM: Kingston DDR3 1333 4G *2
After I switched from Core Processor to Xeon Processor, something went wrong with my computer.The problem is as follows, the computer can turn on normally, but it cannot turn on again after shutting down, unless the motherboard is powered off and the BIOS is cleared, it can start again.It's like static protection.

My motherboard has added 771 microcodes.

When I switched back to Core Processor, the problem disappeared.I don't know how I should solve it.



Forget to turn off the c1e when taking the picture

Do Load Defaults in BIOS.
Make a screenshot of regedit with expanded key HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
