helpWindows can't boot after driver installed

Soft platform: windowXP SP2+WinDDK2003+VC6.0+DriverStudio3.2
Device: PLX9052 switching value input/output PCI card

The problem occured when I used the “Event inform” method to perform the APP to receive a interrupt from the driver. The fucntions of the driver are all OK through debuging the Checked type of driver, but when restart the computer , the computer can’t load windows.

so how can I check where the problem is?
