Tracing Blue Screens
If a system blue screens, use your phone to take a close up picture of the screen. Pay close attention to the IRQ# of the screen. After the system starts back up, track down what IRQ was triggered by generating an IRQ list:
Start->Control Panel->Performance and Maintenance->System->Hardware->Device Manager
Select View, then Resources by Type. Click the IRQ list to open the entire list.
Alt-PrintScreen to capture the image, then open up Accessories->Paint and Control-V to paste this image.
Save this under Desktop->IRQ_List.jpg. This way, if a system blue screens, the offending IRQ can be tracked down.
This image is created by default on newly built systems.
