“STOP: 0xC2” or “STOP: 0x000000C2” Errors!

This means a device driver has caused a WinXP kernel error. I have read this in a PC Magazine called PC Errors and providing the solution as-is. Read On!

A device driver has caused a conflict with the kernel in WinXP, which is the heart of the operating system- the most important code that is used to run applications and manage memory.
A device driver error is like a faulty part on an automobile. The best way to get the operating system running again is to remove the driver. Unlike the “STOP:0x9F” error in WinXP,which unsigned drivers can cause, a signed or unsigned driver can cause the “STOP: 0xC2” error.

The best method for resolving this problem is to think about any new programs you have installed recently or new hardware devices that you have attached and that have installed a driver automatically.
