There is an utilty called driver verifer manager in Windows XP and Windows 2000, it is used to verify whether a driver is OK or not. You can use this utility to find out which driver causes the problem, though you can't do anything to solve it if it is the only driver you have. Maybe uninstall the problematic hardware, looking for a newer driver or write to the hardware company and tell them to solve the problem. Below is information from Microsoft:
 
Driver Verifier is a tool that can monitor one or more kernel-mode drivers to verify that they are not making illegal function calls or causing system corruption. Driver Verifier performs extensive tests and checks on the target drivers. For example, if the driver uses memory at an improper IRQL, improperly calls or releases spin locks and memory allocations, or frees memory pool without first removing any timers, Driver Verifier will issue the appropriate bug check.

I get an email from PowerVR Technologies about 10 minutes after I send them an email about the crashing after quit from 3D games to the desktop. And I use the driver verifier manager to locate the problem causing driver.
