My computer freezes and i get the following message

windows xp error driver irql not less or equal

Plus another line which includes -
usbport.sys

Now the above only happens when i am trying to convert an avi file to mpeg (heavey cpu use?)

anything to do with the new digi cam that i installed ?(uses usb port)

If you can get into safe mode, then use the system restore feature of XP to roll back to a restore point (preferably to a checkpoint before the the event occured)

i've only been getting these problems after installing Raid 0'ing a couple of harddrives. sometimes the error occurs during the bootup of windows or when i'm actually in windows. it seems pretty random.

System:

I actually went as far as getting a new graphics card and installing it, and it didn't help, so I don't know if taking it out and putting it back in will fix much.

IRQ 11 was shared by 2 usb controllers, nvidea graphics card and modem! I/O ports and memory address were shared by my AMD processor to AGP controller and my graphics card!

The only connection I can see is the bloody graphics card!

But, no matter what I do I can't change the IRQ, it just won't let me!!!

Right after mup.sys the video is initialized. I am sure my problem has something to do with video. All my problems only started after I installed the actual nVidia drivers for my Ti4800. I just starting installing this system yesterday. I'm back to running Safe Mode or VGA mode. No problems happen when I'm not running the 'REAL' drivers.

I get this message intermittently when I'm online, but mostly when playing Praetorians and Medieval Total War - often get the Page Fault in . Also these two games have an annoying habit of kicking me out onto the desktop as well. Oh yes or freezing up completely

I'm running an AMD Athlon XP2200+, 256meg of RAM, Invidia Geforce2 MX graphics and Realtek AC97 sound cards.

The shop where I bought the PC have assured me that it's a driver conflict of some sort (which guess what my garauntee doesn't cover) or possibly a conflict caused by one or more Windows XP updates. In short I need to uninstall these, all my games and then try re-installing stuff to see what happens.

The blue screen errors are:

page fault in nonpaged area.
irql not less or equal.
kmode exception not handled.

first if your video card is sharing IRQs with several other devices in your system, change the IRQ the video card is using. This has the be done in your systems BIOS, usually in the advanced settings.

Also, heat will cause rediculous errors to run rampant in your system somewhat un-predictably. If you are not certain the your case has adequate ventalation, download the Winbond temperature monitor and install it on your PC. this software monitors the thermal sensrons on your motherboard and processor and reports the current temperatures. If your CPU is running hotter than 165F you should look into drooping your case temp. Add fans, put it in the freezer, whatever.

Finally, good luck these errors are difficult to track down without a lot of paitence and expierence. Keep as few devices sharing IRQs as possible, also try re-setting your BIOS to fail-safe settings and test it out a bit. If this works, slowy re-enable the rest of your settings and devicesa until the error begins to occure again. Then you have your culprit.

My Story:
I have been using windows xp for somes months. Everything worked fine, only my s3 savage 2000 videocard gave problems. The XP drivers are not offically supported, so I could expect problems. *they actually said, instability could occur. ( see http://lmoschella.tripod.com/graphics_more/id2.html )
2d everything worked well, so I disabled the 3d acceleration under XP, and played games on windows98. Windows 98 has ran withtout problems for 2.5 year. I often made images, (Backup of a operating system), so I always can easily reload a fresh windows, wich should have no problems at all.

When the problems started:
One day, I reinstalled my Windows 98, from XP, with DriveImage2002. I got an error, while writing. As a result of this, I got a halfwritten windows 98 installation. A few hours later, I restored windows 98 again. Now I succeeded. That is, when the problems started. I booted to Windows 98, and Windows says during start-up: "Windows has encountered an error accessing the registry. Windows will fix the error and restart your computer"

Then when going to Windows XP, I eperience instability. IE often freezes, and I need close it. Other programs also die. Now I've too operating systems which both are not that stable. I can still do my work, but programs easily give errors, expecially internet explorer.

What to do?
- I will change the rams chips, cause I suspect there's something wrong with it.
Error 2 of coure, and I read error 4 has something to do with the memory too.
- Install an other graphic card, which I was going to do, anyway.
- Open my case, so all the heat can easiliy flow away.

Wohoo...

It turned out to be a badly placed Network card. I changed it too an another slot, and that did the job.

Tips for people who are experiencing ACPI errors, Page Fault in None Paged area, Himem.sys has detected unreliable xms memory at adress 006284EE XMS driver not installed, and system instability.

Start trouble-shooting. I removed all unnecessarily hardware. So I left the videocard, and installed windows 98. From there I start putting back all the hardware.

(All these problems happen to my machine all while the computer is idle).

1. The Windows XP error "driver_irql_not_less_or_equal" happened to my new machine, it was very brief, it seems that my Audigy soundcard was not seated in the PCI slot good enough. I just took out the card and placed it back, you should all try this, especially your video card.

2. I also receive the dreaded "page_fault_in_nonpaged_area" BSOD. This I have not been able to resolve yet. This happens when trying to format my harddrive within XP's recovery console. Although I do receive this error when I get the random/ daily reboots accompanied with the BCP detail code. (I'm fairly sure this is not heat related due to the fact that the room is air conditioned and all my problems happen only minutes after the computer finally boots. The temp on the CPU is only 113F degrees). This error is typical of a memory issue, I have lessened this occurance by adjusting the memory timings to:
CAS Latency = 3
Active to Precharge Delay = 8
RAS# to CAS# Delay = 4
RAS# Precharge = 4

I have tried tweaking the BIOS settings (ie. lowering my memory timings, disabling USB, upping the voltage for my RAM and AGP slot, though I have not tried disabling the APIC option), but nothing has truly helped.

Everyone having these problems should try looking for a bios update to their motherboard, be careful though since a failed bios update will totally kill your computer. The company that sold you the computer will have the correct bios updates, you cannot always trust the motherboard manufacturer because some boards are specifically built or ordered by the computer companies [DELL, Compaq, HP, etc.]. I have seen bios updates specifically for these problems, unfortunately for myself, the motherboard has jsut hit the market and no updates are available.

Random reboots and possibly other problems could be that the motherboard is shorted against the case, a way to check is to take out the motherboard and place it on cardboard, then run the computer.

I am finally fed-up with this and have ordered a computer diagnostic card and software. It will probably take a week or two for this to arrive, but if I can pinpoint these problems I will post my findings.

Good luck everyone, I'll be floating around and hopefully soon I'll have some answers.

A few pages also suggested bad ram, resetting BIOS, removing all PCI cards, upgrading inadequate power supplies, disabling USBs: http://www.earthv.com/tips_detail.asp?TipID=63

Here's a fix which gives details on changing your BIOS ACPI config which seemed to fix the problem in some cases:
http://www.joshie.com/~jlevitsk/blog/archives/cat_work.html

Some say go into repair mode from the XP install CD, select the drive, and rewrite your boot partition, and check the disk by typing the commands "fixboot" and "chkdsk /p" (I found some anomalies on my disk doing this, although it didn't resolve the issue for me)

As for myself.. after replacing my ram, video cards (AGP and PCI), removing all my PCI cards, changing a heap of settings in BIOS (all of which didn't help), resetting BIOS, fixing up the boot records and errors on my hdd, I finally fixed the problem.

MY FIX: I reinstalled XP over the top of itself.
Like most others, I'm not sure what happened. I left the ACPI disabled, disabled any extra peripherals in BIOS, am using a pretty standard AGP video card, and didn't have any PCI cards when I reinstalled..

AMD XP 2600 333MHZ FSB
1GB 400MHZ DDR (2x512MB)
2xSATA MAXTOR 80GB Drives
Audigy Ex

LG DVD
LG DVD/RW
Logitech Keyboard
Logitech Mouse
Windows XP Pro

I'm having *all* the errors you are talking about, before bios upgrades, after bios upgrades, before windows update, after windows update, before new driver installs, after new driver installs.

I can't say how sick of seeing IRQL_NOT_LESS_THAN I am it's unholy.

I'm also getting 90% of the errors you're talking of on this page - anytime - 2 minutes after boot, 10 minutes after boot, while it's sitting idle, or when it's running a game.

I also have another system:
1.9Ghz Intel
512MB SDRAM
80GB WD
Creative SB Live
Geforce 3.

That runs rock solid in Windows XP Pro

i have just tried a different stick in the sam slot and the same happened,ive tried a different stick now in a different slot and here i am!!

this problem only started after i installed a new AMD athalon XP 2200+.

am i cured???

In the BIOS:
Advanced > Chip Configuration
- SDRAM Configuration > from By SPD to User Define
- SET SDRAM CAS Latency > from 2.5T to 2T. (apparently 2.5T is quite unstable...?)

Works fine for me after 6 months of search a solution, believe me, it`s the solution

However, when I get these errors, and if I can reboot right away (read: I'm at the computer), I can run MemTest86 to check the memory. The interesting thing is that *sometimes* the program reports and error. Somewhere in the area of 192MB or so. Since I'm using NForce2Ultra, I'm not sure how the dual channel memory works. In case it uses striping, then I wouldn't know which stick of ram the error occurs on...if on any of them at all. However, after I switched the ram around, it still dies...and the error is at the same location (when they do appear)...192MB. Therefore, I'm wondering if it's the motherboard overheating.

I've had a system where water was spilled on it (my friend kicked my watercooler setup in the middle of his sleep). It randomly crashed thereon after. Couldn't tell why this was so for half a year...until recently, I realized that three large capacitors next to my CPU had their tops open. Asked some EE friends, and lo and behold, "that's a BAD thing."

So I'm wondering if it's the heat causing the problem...I think I'm going to try and run CPUBurn for a few hours and see how that goes. Maybe another 3D benchmark while I'm at it.

FYI, I don't have that IRQ sharing on my GeForce3, and this is running on an Athlon 2500+ with two sticks of Corsair XMS PC3200 CAS2 (not the super expensive one, the one cheaper than that) 512MBx2. These were the OEM ones with the silver-platinum heat sinks (highly doubt they're made of that material, of course). Maybe the sticker on those RAM sticks cause the over heating? I'm not sure.. The ram is running at PC2700 right now for equivalent bus speed to my 2500+. I'm also using the SN45G from Shuttle...and the ram is located on the other side from the fan. The GeForce3 is a 64MB version from Gainward. (this was salvaged from my old computer...and it had its share of the water when the computer was turned on...but don't think it's this card though)

To say I'm peeved, is an understatement. So here is how I resolved it!

Get an empty Harddrive, install Windows 2000 onto it and piggieback your XP harddrive onto the back.

Remove all the files you need from your XP onto your 2000, wipe your XP.

Format your drive about 10 times (just to be sure), get a priest arounf and have them do the ol' exorcist stuff over it. Now put 2000 onto the drive.

Piggieback in reverse now and get back all the stuff you need. Reinstall any programs you require.

Now, stay the hell away from XP.

I am considering suing Microsoft over the time I spent from upgrading to now. The stuff I've missed out on!

Longhorn!! LOL, you not gonna fix your last rabbit first!!

98 se and 2000 all the way from here.

Lindows too!

Good luck Ya All, Will Keep you updated...

irq error
scsi error
some other system file error
driver unloaded before something error (very annoying)

I reinstalled XP 10+ times over a few months, mainly because I was trying to beat Warcraft 3 and then Homeworld 2 and I didn't want to bebug it while in the middle of a campaign.

After I reinstalled XP 2x in a day, I decided to try out some suggestions and reinstalled with only the basics, nvidia drivers for nforce mb (a7n8x dlx), nvidia drivers for ge force ti ?2? 200 (or 4200?) and of course windows. I played my game (HW2 and it died later that night 4 times and after the 4th time (blue screens everytime), it wouldn't reboot. I reinstalled again and moved my scsi card one slot down (main drive is scsi so can't remove card) with only my vid and scsi scards in.

I installed the OS, my video drivers (not XP compatability certified), DirectX 9 and my nvidia drivers. The VERY FIRST time I rebooted my comp froze at Mup.sys. I had a fit and installed Win2k and I haven't had a blue screen or a game dump of any type.

My theory: Video or Directx 9 incompatibility problem. I was too fed up to isolate it anymore but I would bet money it has to do with my Nvidia drivers and/or my Dx9 drivers.

Something that sparks my curiosity are the number of messages from people saying they have an Nvidia graphics card, a usb mouse, and onboard sound by cmedia. This is the exact configuration I have. I used to have an ATI 8500 and switched to nvidia because somebody told me the problem was ATI. That worked for a little bit but now I get more blue screens than ever before. They usually happen when I'm playing 3d games but sometimes they happen when I'm browsing the web or shutting down. I also have an ASUS motherboard.

spec:
msi k7n2 ilsr delta
2400XP
ti4200
512 crucial
WD raptor

Fine, no problems whatsoever with my ati rage pro 128 32mb, as soon as i stick in ti4200 probs are there, stable as anything til i try to install drivers, as soon as i attmpt to install them bost with the page file not equal error, is always the same file, cant remember the name tho :( something like md4_something.

totally stable with the ati its just with the nvidia that there's probs :(

What is your exact system setup?
I have an
Athlon XP 2600
Asus VIA K7V600
GeForce 4 4200 TI 8X AGP
512MB of Black Diamond Mem
Two 30GB Maxtor ATA 133
Verbatim (LiteOn) CDRW

I've run into the same problems with XP Home, XP Pro, XP Pro pirated, Win 2000 pirated.

The most success I've had is in updating my nvidia card to the newest drivers 5.3.0.3.

I'm going to go try each of the options suggested here that I have yet to try. (I've been working on this problem for three months.)

I have switched Memory, switched graphics cards, turned off CD-Rom, used one hard drive, changed CPU VCore and updated each Windows to the max.

I'm really tempted to go back to Linux and see if this still happens...

Me too.. If i try to play a game, for example fifa 2004, i play for 5-20 seconds and then it throws me back to windows or gives me a bluescreen saying PAGE_FAULT_IN_NONPAGED_AREA and mentions nv4_disp.dll.

I have tried two different cards: GeForce fx 5200 (Asus V9520 Video Suite GeForce FX 5200) and GeForce 3 (Elsa Gladiac 920).
I have tried different driver versions for the cards and also for my motherboard k7n2 delta-ilsr, which i bought recently and which with i have had nothing but a problem after another..

Removed suspect program '7-Max', defragmented my pagefile completely with Diskeeper 8, installed the latest C-Media drivers (below), and disabled Xear 3D in the C-Media control panel, and the blue screens have stopped.

How can a "poor" windows user deal with this problem, when all professional guys are really lost with this??

After another hundreds reading, I learned about two possible solutions for this IRQL ERROR:

a) In the BIOS -advanced - Chip configuration:

SDRAM configuration: from By SPD to User Define
and
SET SDRAM CAS Latency: from 2.5T to 2T

b) In the BIOS:

disable HT (Hyper Threading)

and also: try to update each driver of each hardware you have...
if there is no xp driver in the appropriate site.. buy an other hardware!!
exemple:
d-link fm usb radio.. go to hell no xp driver!
old epson printer 740 : no xp driver!!
old first generation hauppauge TV pci card
no GOOd xp driver!!...
change your hardware.. it's better.. for the new year!

This should work for everyone. I won't go into why it works, but there's a 90% chance it will work for everyone!

Restart your computer, and go into the BIOS setup. DISABLE nearly everything! USB Ports, parallel ports, onboard sound, onboard modem's and network cards, un-used pci slots, un-used ide channels. Everything with exception of your graphics card. Restart with your XP disc in the CDROM (you must be able to boot from CD-Rom) RE-Install XP, deleting any partitions, and formatting your hard-drive (don't take the quick option) continue to install XP. Once you're up and running XP. restart your computer, go back into BIOS, and start re-enabling your components (start with network cards and modems and finish with the USB ports) Enable one thing, then do a restart, go into XP and check all is well, then move onto the next thing. I GUARANTEE this will work on 90% of all machines.

I have a ASUS P4S8X motherboard with an "onboard soundcard". And this was my problem. Everytime i tried to play Battlefield 1942 the bluscreen appeard. So I went out into my "BIOS" and DISABLED the "onboard soundcard" wich was on "Auto". Now I dont have any sound, but rather that then getting my computer shut down every 15 minute. And I will offcourse buy another soundcard.

(Tip: This only happend when I used my computer to the max. It was really working hard. In some cases I have heard that "Norton" is the main cause to this problem. I will uninstall Norton and install AVG instead.)

Hope you'll figure it out!

What really bugs me is that I'm not allowed to open the machine (voids warranty), I've had it in for repair at least 5 times, and they have changed the processor, which helped for a couple of months, but lately they have blamed drivers, reinstalled them and after a few weeks the problems are back.

I av experiencing these problems when I play games, such as Neverwinter Nights, Homeworld 2, Star Wars KOTOR and other relatively new games.

If you come up with a solution, please email me at arnehed@telia.com.

Thanks in advance.

This article describes the steps involved in restoring your registry in Windows XP

MY SOLUTION was to change the RAM speed in the BIOS.
It was set on 'Auto', I did set it on 266MHz manually.
Since then I have no crashes at all when I use 3D
games.

My conclusion:
This is more an harware problem rather than a software
problem.
It is a hard problem to solve, it requires patience
and a step by step plannification work. Writte down

the action you have taken and the one you will take
(this forum contains a lot of different possibilites
of actions - select the one that are relevant for you
and rank these). This will help you greatly to solve
the problem. Otherwise you will forget which action
you took or not and be finally totaly lost.

My specs:
AMD motherboard ASUS A7V8X-X
GeForce FX 5200

I've just bought a:
shuttle SN45G
XP3200
2 x Crucial 512mb 400Mhz dimms
Maxtor 120Gb Hdd
& am using a Geforce3 card (will upgrade to 9600XT next pay day!).

I put it all together last night, but XP won't install ;[
Lots of blue screens (irql, paged in nonpaged etc...), frooze a few times...in short a pain in the @rse.
Each time it seemed to get a bit further, after trying various settings. I'm convinved it's because of all of the onboard bits & bobs (5.1 audio, Networking, USB2, Firewire, Optical in/out), but can't find a way to dissable this to do a minmal install.
Got a BIOS update to try tonight, some different RAM (266MHz borrowed from a work PC) & a Gefocre2 MX400...Also I read that USB mice can cause the problem, so I'll be swapping that too!

got my system working (finally). After much faffing around in the bios, I got XP to install by underclocking the 3200XP to an "1100XP". As soon as I was patched & updated, went back in to try & boast the cpu to it's normal level..the result...WON'T BOOT!! Falls over just prior to login screen (or mup.sys in safe mode).
Now finally have it running stably at 2500XP level (333 FSB). Not happy about this as I expected to get at least the minimum spec out of the processor & RAM (i.e. 400MHz FSB & 3200XP).

I sure wish people around here would get this problem.. I could make a lot of money repairing these things! :)

I got constant bluescreens doing different things, sometime installing an app och just surfin the net.
I checked the Asus website, and found out that my memory wasn't in their supported list of pc3200 400 memorys..There were some Samsung but the numbers on the mem and on the chip wasn't the same..
So i tried to use 2 older memorys that i hade in my old com, 2*256mb DDR PC2100 Samsung mem..
And now it's been running fine..
I guess it doesn't matter which older mem u use because there are no compatiblelist for more than pc3200 mems..
So i think this Bluescreen issue is memory related...

Never mind the local 'community' shops.

I still have the prob, but I downloaded "Deep blue" into my hardrive and told it if it didn't at least hold it together a bit better I'd kick it's ASS!!!

Nobody got a solution for this yet?
Microsoft must have had enough 'feedback updates' to resolve this..

..oh yeah, it'll be in Longhorn Servicepack 101
