Blue Screen Error - irql_driver_equal or less

Question: I got a blue screen error (irql_driver_equal or less) while installing my operating system.
Answer: Automatic reboots can be caused by several different things and are hard to diagnose. One thing you can try is turn off the automatic reboot option under the recovery options for your computer. This will make it so your computer won’t reboot on errors so you can see any problems. Here is how you do it.
1. Right click My Computer, and then click Properties.
2. Click the Advanced tab.
3. Under Startup and Recovery, click Settings to open the Startup and Recovery dialog box.
4. Clear the Automatically restart check box, and click Ok until all the windows are closed.
5. Restart your computer.
The next thing to look at is to see if you have installed any new software or drivers or even any new hardware on your system. Faulty drivers can cause reboots as well. If so you may want to uninstall the software or remove the new hardware and see what happens. Roxio 5.0 is known for causing this problem.
There can possibly be a problem with your motherboard's BIOS. You may want to do a BIOS update if there is one available. Just be really careful to do it correctly because you can ruin your motherboard if you don't.
