DRIVER_IRQL_NOT_LESS_OR_EQUAL Windows XP

by XAkitAX / August 18, 2006 3:03 PM PDT

I recently upgraded my computer and i keep getting automatic restarts. I get a blue screen that says:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

I copied the page and it says:

Check to make sure new hardware/software is installed properly. If its a new installation, check for updates.
If it continues, remove new hardware/software, disable bios memory actions such as caching or shadowing.

Then there is tech info, which I didn't copy.

Then it ends with: Beginning dump of physical memory.
Physical memory dump complete.
Contact system administrator.

My system consists of:
EVGA nForce4 SLI microATK mainboard
EVGA 7600 GT KO 256 MB PCIe
AMD Athlon 64 3700+ San Diego core
1 GB of Mushkin Ram PC 3200
WD 120 gb hardrive (its not SATA so i have it connected on CD Rom line as master)

When I installed my new hardware, I didn't reformat my drive. I already did the virtual memory trick from another discussion, but I just got another restart.
Hope all my info helps! Thanks in advance.

AH!

Understand that Windows has a component called the HAL; and this HAL is specific to each computer its installed on. The IRQ_LESS_THAN_OR_NOT_EQUAL error is given when a driver doesnt respond in the manner in which it should. In this case, the entire HAL would not be responding the way it should because its on new hardware.

From your install CD you will need to run a repair operation to install the proper core system drivers and virtual devices. Dont worry, all your stuff will still be there, or at least it should if Microsoft is on your side that day! Wink

Thanks, i'll that. I also noticed none of my floppys will work either. I have the cable in right and everything. That might be because of this IRQ problem too.

How do I repair?
by XAkitAX / August 19, 2006 3:16 AM PDT

Im back. Can you be more specific on how to repair? I restarted my computer with windows in, and hit repair. It took me to a command prompt, and I didn't really know what to do. How exactly do you repair?

You need to boot to your Windows XP installation CD to perform a REPAIR INSTALLATION.

Hi, I have a toshiba satellite L350d, it use to have a 2gb memory 2x1GB (PC2 5300s)
Now I bought 2x2GB (PC2 5300s) to get a 4GB and installed both but when I switch on my laptop I get the BSoD with Driver_IRQL_Not_LEss_OR_EQUAL error with ataport.sys

Address 814A2AE1
base at 81499000
Datestamp 49ee8a3a

Currently running Windows 7
Both 2GB memory sticks works fine individually though

Any help would be most welcome. thank YoU

Your instructions were able to get me past the blue screen to the desktop where I could contact my tech people.
Thanks so much,

Possibly overheating
by JustinPS / October 26, 2009 3:08 PM PDT

Sometimes this error message will come up if certain hardware in your computer is overheating. Usually your RAM is the culprit, especially if you just installed new RAM. I would suggest either buying heat sinks for the RAM to help dissipate the heat, or if it's a laptop, buying one of those platforms with fans attached that sits beneath the laptop to help cool it.

Again, this is SOMETIMES caused by overheating hardware (usually RAM). I would definitely try repairing Windows as m_and_m_kid suggested before worrying about your RAM, though.
