Blue Screen Error Irql_not_less_or_equal

Have you gotten a blue screen error that says the following:

IRQL_NOT_LESS_ OR_EQUAL

Typically what happens is suddenly you will get a windows blue screen (aka blue screen of death or BSOD) and the command prompt will read that particular message. Then your computer crashes and you are required to reboot. What causes this problem? It could be a couple of things.

First your computer may be overheating. Feel your computer (especially if you have a laptop) and check if it is running hot. If the temperature feels abnormally high it may be a good idea to get a cooling fan. You should also be running your computer on a smooth cool surface.

The second and most probable cause of the blue screen error Irql_Not_Less_Or_Equal is an issue with your Windows registry, more specifically the HAL layer. HAL stands for the hardware abstraction layer. It a process in the Windows registry that communicates information from the drivers to the hardware.

When there are errors or corrupt files in your registry, then HAL cannot communicate with your hardware. This will cause your computer to freeze up and give you the blue screen error – Irql Not Less Or Equal.

While this is a very complicated issue, fixing it can be rather easy. You cannot do it on your own unless you are an absolute computer expert. But fortunately there can be a very simple solution. Scan your computer with a registry repair program that can fix problems in the HAL layer. I use such a program myself with great success.

dell 1501 laptop screen issues?

i have a dell 1501 laptop if the screen is open and you turn the computer on you can log in and have no screen issues. as soon as i close the screen and reopen it the computer turns back on but the screen doesn't stay a solid picture. it looks like cracks and almost static like. any ideas??

If you log onto safe mode, do you have the same issue? This happens after awakning from sleep or hibernate but it's OK when turning it on from a full shutdown?

It is likely you need to reinstall notebook system software, reboot and intel chipset driver then reboot again. The 1501 usually uses integrated video. If you have an ATI card reinstall that too. Go to support.dell.com

It might not be the video driver, it might also be an issue with another piece of hardware not waking from sleep or hibernate well. webcams and bluetooth 2.0 devices are famous for this. Uninstall the bluetooth devices and see if the problem persists.

You might also want to create a new power profile and disable hibernation.
