What is an IRQ?
There doesn’t seem to be any direct cause of this Blue Screen of Death error message. The most likely cause seem to be faulty or bad RAM. So, make sure you’re grounded, open up your computer case and make sure the RAM is properly seated. You should not be able to see the gold contacts. If you bought cheap RAM, you may want to return it and buy from a well-known company, such as Kingston.
Other possible causes include the video card (NVidia seems to be a culprit), or the sound card. Try swapping these components for others and see if the problem reoccurs.
You can also try running RAM tests using Memtest or Simmtester.com
Another cause could be overheating, and Windows may just be guessing the problem. Make sure the case has proper air flow.
You may be able to figure out the problem in the Event Viewer, Control Panel>Administrative Tools>Event Viewer.
The best way to avoid IRQ conflicts to is install expansion cards one at a time AFTER installing Windows.
