This PC will just reboot at various times.
To stop the reboot and cause the PC to stop and show the error
you deed to get into the Control Panel, System, Advanved Settings of the Startup and Recovery
and untick the option to restart on system error

After I did the above, when the next crash occurred the system stopped with a Blue Screen crash error stop D1

This error is related to the Linksys Wireless G PCI Adapter

The solution was to remove and replace the Wireless G PCI Adapter.
