hi all,

I have a serious problem with my HP laptop (latest model)
i bought me a wireless pcmcia card from topcom skyrace 3044 to go on the net wireless.
But since I installed the car I have always a rest of my computer, a blue screen is appearing with next message
driver irql not less or equal
I work with Windows XP home edition (included from the HP laptop)

whatever i do, nothing works, norton disabled, uninstalled.
when the card isn't injected , the pc works properly.
Even , but very sometime, the computers works for 2 hours and than without doing something, ploep crashes again with the same problem.
updated win xp is allready done.

What can I do? please help me

That means that the driver you installed isn't fully compatible with XP. Not much you can do besides uninstalling the driver or finding a compatible one.

I ve problem whit my pc....everytime I try to download my system arrest and appear the blu message " driver IRQL_LESS_OR_EQUAL " .If I only use internet the problem doesn`t appear....What`s the problem in downloading ?
Is there someone so kind who can help me ?

In my particular case, it happend to be a bad RAM card. If you have at least two, you can try to remove one of them and see if it still crashes. If it does, remove the other one. if it still crashes...well, thatīs not the problem

Sometimes you can verify inmediately by changing the position of the RAM cards. One of the difficulties with this kind of problems is that the blue screen appears randomly (only wen the computer uses the broken part of the memory). By putting in the first slot the defective memory stick, it will be used earlier, and the crash can appear just in the booting.

i was so happy being a shepherd...

try another card.

I am having the same problem when running games, at certain points during the games ( Medal of honour, hidden and dangerous 2, and knights of the old republic etc) I get the error message which led me to believe that it was the graphics card playing up, I have an Nvidia gforce 4 128, can you tell if its definately this or, reading through the other posts could it be any card?

Hey people,
I have also been having problems with IRQL driver being less or not equal. I have also been looking for drivers that could be causing this, but with no luck. Today i reinstalled everything on my computer, to find the same problem happening all over again. But reading this board got me thinking. I think the problem started after i upgraded my mermory. So i will try going a week without this new memory stick, and if that help "Crucial" is going to get it right back in their faces.
Wish me luck..

Just for your information. I have had this same problem for over a year now. I have installed all different types of Windows that are available (XP, ME, 98se, 98 and 2000) I have gotten the exact same on all the OS systems. I have tried several different new memory stick and the issue is still there. I have installed new power supplies and you can guess, it didn't do a thing. The issue has to do with the IRQ steering on the board. This issue is an issue that will continue to increase the more advanced computers will get. The base system these days allows only a certain number of IRQs. When the number is taken up the system starts sharing/steering the IRQs onto the same IRQ. The most common use is IRQ 11. Most coms work because the board/Windows steers these correct not allowing devices that are used most often to share the same IRQ. My board K7S5A (ECS) sets my audio driver and the Ethernet card on the same IRQ. So when I get the blue screen of death it is when I am online playin video games or using Graphic Software while online. The term for this insanity is called an IRQ storm. Now, I'm using my com till it crashes and saving more frequently then every. But, to make the idea evn more interesting this has happened since I bought the damn computer. =) So, if anyone can tell me anything that will help understand how to fix this it would be much enjoyed.

I run Win 2000Pro. I've been getting this error and a variety of others for several months , since I did all the MS required updates. I do not play any games, have not installed any new hardware or software. Have a dial up modem and not currently even a printer installed. I do very simple things go online read my email and read yahoo groups. Sometimes copy various passages to MS Word . Not often I download some texts.
Sometimes I copy photos. For the last several months I have blue screen after blue screen , a variety of error messages. I've defragmented my disks, run virus scanning online - nothing, and all I'm doing to correct it is restart, shut down, over and over til I can eventually get up. Today it took about 4 hours over and over. Just now got up. Yesterday was up most of day.
Not getting better. Getting worse.

Hey,

Im haveing this problem trying to install on my computer. It gets to the point after formating the hardrive and startes to start up windows and it says driver irql not less or equal. And all the parts are brand new. I have tried reseating the ram, tried it with one stick, tried differant cd drives, and differant hardrives but it keeps comeing up with the same error. Does anybody know whats up.

hi all

I ' ve the same problem. If I open kazaa or emule for downloading anythings i have a blue screen with DRIVER IRQL NOT LESS OR EQAL. Can somebody say me, what's the problem??

Thanks very much...

A simple thing to try to resolve this is, if you have any more ports/slots just jiggle the perepherals about a bit. I get IRQL if I put anythig directly under my graphics card, if i move whatever is underneath and it is assigned a new irq which I would assume happens to the driver too when I reinstall that hardware.

(in the past week I have been problem solving all over the place usually 95% of the time my advice has helped, one thing that got me down as a whole is having to register with every forum I helped in. I am now a member in more than 20 forums lol) if you fancy visiting mine it's called Techvana

I have the exact same problem.
I got the svchost.exe virus file in my drivers folder, and my anti-virus removed it...but now my computer keeps showing that screen at random intervals. Driver IRL Not Less or Equal - but sometimes it just turns off the screen, and it wont turn on again. I have re-installed Windows, and that didn't fix it. I've tried lots of online virus scans and I use AVG - still no result. Heeeeelp =(

I have the same problem, however in my case it seems to be connented with my hard drive.

After I played a little with partitioning of my drive in order to reinstal windows, IRQL_LESS_OR_EQUAL starts to break windows installation. When I connect this drive to another PC windows stratup breaks too! When the drive is disconnected - it is OK again.

I thought that my harddrive is broken or misfuctioning or maybe I've broken it somehow during partitioning. Under pure ms-dos it seems to be working (fdisk finds partitions). What I suppose is imortant - this drive with the same motherboard, memory etc. worked for more than a years before this strange things began.
And it was possble to connect it to the second pc without any trouble.

If you have any ideas I will highly appreciate it!

I have this problem also. I am using an ati 9000 128mb graphics card and I've found that for me it is a graphical error. What I was wondering was if I change to a different brand of card would this solve the situation.

Hi All

I was reading your posts and what I heard through a couple of buddies of mine overheating could be causing this as well. There are freeware programs out there that force your fan on your laptop to run all the time.

It might be worth a try to have it run to see if this could be causing the issue.

hey everybody, i am having the same problem with my laptop, i bought it from dell, and i am running windows xp pro and it is giving me all kinds of error, from irql not less or equal, to bad pool caller, to others, i ran diagonistics on it but it didn't detect anything, if anybody can help me please i appreaciate.

Hi people, Like all of you I have had the same problem, running a Expox 8rda+ mother board with AMP XP2800 and two chips of DDR ram installed, Gforce 5900 graphics card...and here is what i found..I changed the graphics card to a ATI9000 pro and the problem seemed to go away but the more I taxed the machine, boom it was back so it wasn't the graphics card, but why would one get less errors, I thought it must be the memory so I ran the test on memory all night and no errors but I didn't believe the results so since I had two I took both out to check them and found that one was a ddr 2700 running at 333 and the other was ddr3200 running at 400 and there was the problem. I put just one back in and taxed my machine as much as I could and got no errors.....this might not be your problem but its something to look at.

Ok so im obviously having the same problem. I looked at what one of you said a few posts back about overheating. my computer has been overheating A LOT! lately, and just shutting itself off. So i talked with a few people, one of them mentioned removing a stick of ram (im running 768mb) so i took out 256, and ever since doing that, ive been getting this BSOD that points to IRQL_NOT_LESS_OR_EQUAL and mentions the ndis.sys driver. so i think maybe this is a ram problem. so what ive done is gone to (in win xp):
right click on my computer, go to advanced, click on settings in performance, go to advanced and click on CHANGE in the virtual memory section. In there i selected no paging file and clicked SET. then ok ok ok. So im hoping this works, after doing this i restarted my computer and havent had the problem yet, i will update you to see if this works. hopefully it does.

ok so ive gone almost 24 hours without a BSoD, SO! just as my last message says, go into your system properties (in control panel or right click on my computer>PROPERTIES) go to advanced, performance settings, advanced, virtual memory(CHANGE), and set to NO PAGING FILE. Click set. You'll be prompted just click ok. ok ok. So thats it, this seems to have worked in my case, let me know if it works with yours...

I had this problem too. Everytime, during system boot, blue screen appeared with this error message, and system has been immediately restarted. But no new hardware has been added, no new software installed. I really don't know why Windows has been doing that to me. After reading these posts, I found that three of my PCI cards have the same IRQ number (in table displayed while booting). I changed their possitions for few times, and now each device has unique IRQ number. Problem has gone. Thank you all.
