Boot error IRQL_LESS_OR_EQUAL.

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...

you could spend all day trying to resolve this.youd be better off starting pc with xp disk in drive and boot from disk.then in option install os or repair choose install.system will check for existing os and ask if sure to install..verify.(yes,(y) agree)in next screen option asks install xp in location or repair;at this point now you can choose repair(the first choice is a dos platform )
