Re: IRQL_Not_Less_Than_Or_Equal - Any ideas?
Actually everyone who has posted above is correct. Dependingon te stop error, it could be any number of devices, peripherals or components presenting the problem. I have had this experience many times with a Hp ZV5000 laptop. It was not the RAM as others had suggested, not the DVDRW/CDRW drive, the screen, the touchpad, the audio or video card, not even the touchpad, card reader or Cardbus controller. It turned out to be a DRIVER. Even using Compaq's driver CD presented the same problem. I got my hands on some older drivers (the audio was the main culprit) and viola! everything returned to normal. I suggest you start windows in safe mode (F8 will access the boot options) and rollback/uninstall the last driver you installed/updated. If that does not help, continue the process with the driver you installed prior to that and you SHOULD be able to overcome the problem. Hope this helps
