When you attempt to shutdown Windows 2000, the computer hangs on a blank screen and the mouse pointer and/or keyboard is non-responsive.
If you do NOT have a floppy controller, the Standard Floppy Disk Controller in Device Manager displays:
This device cannot find enough free resources that it can use. (Code 12)
When you shut down from Safe mode, you receive:
If you have PACE Interlok anti-piracy software installed, the Tpkd.sys driver uses the same IRQ as the Standard Floppy Disk Controller, which causes the conflict.
Download Tpkd.zip, unzip, and install it.
