You mean Windows Protection Error

All the suggestions below can cause the above error message

If a real-mode driver and a protected-mode driver are in conflict.
If the registry is damaged.
If either the Win.com file or the Command.com file are infected with a virus, or if either of the files are damaged.
If a protected-mode driver is loaded from the System.ini file and the driver is already initialized.
If there is a physical input/output (I/O) address conflict or a random access memory (RAM) address conflict.
If there are incorrect (CMOS) settings for a built-in peripheral device (such as cache settings, CPU timing, hard disks, and so on).
If the Plug and Play feature of the computer's basic input/output system (BIOS) is not working correctly.
If the computer contains a malfunctioning cache or malfunctioning memory.
If the computer's motherboard is not working properly.
