Reformatting is a little drastic.

This is a somewhat common driver error - when your machine sends out the signal to devices to shut down, one of them is throwing errors (bad ones) in the shut-down process. You need to find the hardware (or less likely, software) device that is not shutting down properly.

It is very often video drivers; try changing your video drivers to the Microsoft defaults and then shutting down, rebooting, and shutting down again. If the IRQ error does not turn up, you have a video driver error, and need to visit the HP web site and get the latest video drivers for that laptop model.

If it is not the video driver, you need to look into what new drivers or devices have been installed that might be non-standard. Unplug the laptop from everything that plugs in - USB devices, printers, SD and USB memory devices, hubs, everything. If this fixes the problem work backwards until you have re-installed the problem device and try to uninstall and install it again with the latest drivers.

It might also be the wireless network facility not shutting down properly. Try shutting this off in the hardware (with the wireless button on the keybaord) and DISABLING it in network settings and try shutting down.

Once you find the hardware device that is not shutting down properly, UNINSTALLING it in the DEVICE MANAGER and then rebooting and reinstalling it from scratch with the latest drivers usually works.

Good luck...

Keep getting an error message irql not less or equal and system reboots. what do i do

IRQL errors are generally software/driver induced.
1st see if you can boot to the safe mode (F8 at boot) and get into windows.
If you can try a system restore to before the issue started.
If you can't get into windows, try Fn + power and run diagnostics on the system, you may have a bad hard drive.

irql not less or equal sounds like a graphics driver problem. All you needed to do was boot up in safe mode and remove the gfx driver and the OS would have rebooted with the default driver and then you could have reinstalled it
