Windows 10 crashes when multi-processor is enabled in Bios

[Dudden]

The PC shut down without warning. When I started the computer back up I got a windows blue screen saying critical process died and reboot after reboot the same error occured.  I ran the diagnostics tests on the hardware and all passed. By process of elimination windows only starts when the bios option multi-processor is disabled. All windows updates/drivers/bios are updated to the latest versions but when enabling the bios option again the problem still occurs. Disabling the option and starting up windows the CPU is only showing one core when I expected 4 (see below)

 

Is the CPU damaged or is it something else as even using the recovery utility does not resolve the issue. Thanks

I say "something else".

The only way to be sure is to find a "spare" disk-drive, remove the current disk-drive (containing your personal files), connect the "spare" disk-drive, enable all the cores, and install Windows onto that "spare" disk-drive.

If it installs & works, then your hardware (excluding your "primary" disk-drive) is OK.

If it fails, then your hardware has a problem.

If this install worked, then "clone" your original disk-drive onto that "spare" disk-drive. 

If the "disk-cloning" encounters any problems reading from your original disk-drive, then your original disk-drive is "suspect". 

If the cloning succeeds, then you can assume that the "spare" disk-drive is physically OK.

Boot from the "spare" disk-drive.  If you get the original symptoms, then you have a "logical" problem -- corrupted installation of Windows on both disk-drives -- not a "physical" problem with the "spare" disk-drive.

Thank you so much for your assistance on this issue. Spare disk drive now plugged in with all cores enabled but for some reason even booting from a windows 10 boot disk just hangs and all usb devices just disable. It looks like a hardware issue. Thanks again 🙂

If those USB devices go "dark" (no lamps on keyboard), no light from "laser" mouse, when you're asked to select a language, you have a SOFTWARE problem.  Windows tried to load its own device-drivers for the USB hardware on the motherboard, but failed, because you booted from a "generic" Windows 10 disk, instead of an HP-customized version of Windows 10, which would have loaded the correct device-drivers for the USB hardware.

Expressed more briefly, if you boot HP software on your HP computer, your hardware will work, because the necessary device-drivers will be loaded.
