im running windows xp pro,everything runs great even UT but occasionally during UT the system reboots itself,this only ever happens playing UT,i have all latest drivers and patches,ive tried running it in compatibility mode,ive disabled workstation services ,reinstalled windows using both ntfs and fat32, as well as re installing ut but am now stuck for ideas,can anyone help please.pc spec
amd thunderbird 1.2,asus a7v133 with latest bios update,hercules geforce 2,guilemot muse sound card364 meg branded ram.

You are experiencing a System Failure while playing and this is causing the reboot. You can stop the reboot from automatically happening in the Control Panel somewhere. SOrry I dont exsactly remember where. There is a checkbox that is selected by default in XP to reboot the box. It you uncheck it, you will get a bluie screen with an error message instead that will help you debug it. Probably a driver problem my guess.

It sounds as if your PC is producing a Blue screen and then automatically rebooting.
You can turn off the reboot so you can see the full error
To do this
Control Panel/System/Advanced/Start-up recovery
Remove the tick in "Automatically Restart"Now you should get a blue screen rather than the reboot.
Generally it is an Incompatible driver, Antivirus software or an incompatible app.
There are also many other reasons.It will be worth posting the Blue screen details on this board.
Have Fun!
Super Play

The other guys are right, but WHY are you
getting a fatal error?Maybe your CPU or Vid card are getting
too hot and causing the system to be
unstable.Play the game again, until it crashes.
Then in the BIOS look at the CPU temp, is
it hot? (more than 60c is HOT).Maybe you need a better heatsink? Or
more case cooling.

Ive checked the temperature of the motherboard and cpu,i ran the utility and recorded the data till it crashed,,both where running well under the threshold and at a constant temperature,,so ill try the check box to get the error message,,funny enough today it constantly rebooted as soon as it got into windows,this is the first time its done this ,but thanks for the advice at least i can rule things out now,,,ill go do the check box to get the blue screen and post any findings,,thnx again

ok i set it to blue scrren and this is what i got.
during game play:
IRQL_NOT_LESS_OR_EQUAL
stop:0x0000000a(0xff5f7980,0x000000ff,0x00000000,0x804effb6)..................................
during reboot it happened getting onto the desktop,,i got
win32k.sys
page fault in non paged are
stop:0x00000050(0x96ddd4f0,0x00000000,0xbf8f10ae,0x00000000)win32k.sys address bf8f10ae base at bf800000,date stamp 3b7de698
................................
nexr boot i got:
0x0000008e(0xc0000005,0xbf84113f,0xf34eba14,0x00000000)win32k.sys address bf4113f base at bf800000 datestamp 3b7de698.
....................
next boot went ok.
....................
does this mean anything to anyone or could anyone tell me where i can find out what it means..
thanx..

Do you run Blackice Defender?This is probably old news but awhile back some of us were having problems with auto reboots.I uninstalled Blackice and havent had a reboot since.I havent checked Blackice web page for awhile so there might even be a fix by now.I dont know squat about computers but thats my two cents.Good luck!

I am having the exact same problem same error msg an everything when playing any 3d game, i too have all the latest drivers and bios, cant understand why, any suggestions would be great!!!!!!!!!!!!!!!

i have no firewalls running at all,but over the last few days the pc has just started rebooting on its own soon as its got onto the desktop,im totally stuck now,ive removed the sound card and driver also removed the vid driver and using windows own geforce driver,,,i think maybe time to either re install windows xp or go back to millenium,,unless someone knows what it is,,progs installed:cd copy,hotburn,microsoft office 2000,avg antivirus,cute ftp pro,roger wilco,get right and thats it,they where already installed and working fine before my problem started.
ps.steve if you ever find a solution an e-mail with the fix would be greatly apreciated.

i now have system running fine,,fungers crossed,what ive done is,,before i had updated bios hard drive had to go on last plug of ide cable for it to work,,dont know why but now it is in the correct order,firsr socket of ide cable with cd slave on the last as well as other drives on secondry ide,,ok,i made restore points after every bit of hardware and program i installed,windows xp and unreal tornament only on pc,runs great no sound card installed,installed zone alarm then avg antivirus,,crashed after avg went on,,uninstalled avg used norton 2002 instead,runs fine,,installed guilemot muse sound card with the cmi783 driver and not the manufacturer driver,,loaded other software and pc is running great,so all i can presume is a combination of avg antivirus and the muse sound driver,,if it helps anyone thats great,if not well at least i got my pc running,thanks for everyones help,,
cheers

well it ran fine for about 5 hours then started again so maybe i go back to windows me again.:(

I've read at the ghost recon forum site of newest det. drivers not exactly working the greatest with XP. I had problems with 23.11 and switch to 21.83, problems solved. For more info on this try reading forums at ghostrecon.net.

I'm currently running a lot of 3d games off my computer, including UT....although now i just have UT on my computer, regardless i'm still getting the win32k.sys error, page faults and irqls etc. etc....temeperatures are fine...is there some sort of debugger that i could get or some sort of system analyzer that would help me identify and clean up any errors and incompatiblities between whatever drivers i have that's causing this problem? i'm using XP drivers only as well, for vid card, sound card etc....but this problem has been plaguing me for months....using both fat32 ntfs, then switching back to fat32...still have same problems..any helps?

I have the same problem.While playing any movie , the system reboots itself. Is this a problem specific to WIN XP ? I haven't tried any other OS yet.
Hoping to get some help.

Me too.
I have had XP for 4 weeks, Radeon 8500, AMD 1800XP and Gigabyte 7dxr. I am running at 100MHZ till my board is replaced (known problem) but I frequently get stop errors. Some unidentified, but most recently they are all win32k.sys errors at the same address. - b6f8c198.
I would like to find out what this is and mem ranges in winmsd doesn't help much.
Any ideas?

im having the same problem, a blue screen with win32k.sys while running a 3d game.
although my temperatures are fine, and i dont remember having the probs a few weeks ago... so i looked hgat has changed in this time... the only thing i changed is my vid driver for my geforce 2 gts... running 23.11, tried 23.12 but it doesnt work to... i switch now back 21.83... hope it will work... will post the result...
pc specs: athlon xp 1600+, 512mb ram, epox-8kta3,geforce 2 gts 32md ddrgreetz...

this didnt work as fine as i hoped... i installed 21.81 detonator drivers... non whql certified... i could play medal of honor, without errors, but when i wanted to exitthe game, i got a bluescreen... nv4_disp.dll error... page_fault_in_nonpaged_area...
i know this error... usually it means youre drivers are to old... so i had to switch back 23.12... and it still does not work... think i will reinstall windows xp pro when i have time for... no medal of honor for awhile... :-( ...greetz

I had this happen consistently until I switched my desktop back from 32bit color to 16bit color. Give it a try.

have you all been running roger wilco when this happens? so far I have found that this seems to be the cause.

Go into your bios and make sure you disable video bios shadowing for your video card.
This should solve your Win32k.sys crashing problem. This is a serious bug, as two areas of memory are being attempted to be written to simultaneously.
Let me know if this helps.

I have also gotten the IRQL_NOT_LESS_OR_EQUAL error on a new system I built. After looking at several forums I found what I think is the answer. If your system is set to ACPI complient, you may have an excessive amount of devices sitting on IRQ 11. What I did to correct this is to set my computer to a standard PC. You can do this by changing the driver for your computer in Device Manager. I have done this and it gives you MB back control of the IRQ's. I have not had a problem since. WARNING******Win XP will find all of your hardware again. Back up your drivers for any devices that are not using the standard Win XP drivers. Hope this helps!

I was having the same problem...
Solution: Uninstall your anti-virus software!
If not resolve...try remove any cdr recorder program

My system was running fine and I wasn't running any anti-virus software. I copped a virus and had to reinstall so I chucked NAV2002 on and ever since I've been having the same problems, win2k.sys and IRQL_NOT_LESS_OR_EQUAL etc. I uninstalled Anit-Virus software and now it runs fine.
So uninstall any anit-virus software!!!

I was having the same problem playing Urban Terror. The way I fixed it was to set the MB to Fail-Safe. Then, when I walked the settings back up to Optimal, it started crashing again. I have an Asus K7 / AMD 1.4 / GeForce2 Ultra. I think it is in the MB bios

I am having the same reboot problems...the blue screen with the error messages...I have ECS K7S5a/AMD 1.4/GeForce 2 MX 400

jezzz... and i thought it was bad that i was having performance issues with my video card and xp

Mine does this too; Duron 1.0/256mb/20gb-ata100/ati xpert2000/sb live value. XP Pro upgradfe from 98se (i know). Today I get good events:
From Event Viewer:
"Error code 1000008e, parameter1 c0000005, parameter2 bf83f56c, parameter3 f2a40fbc, parameter4 00000000."
Note the c0000005 = this was once a problem with DCOM components, and is always caused by conflicting software modules... DCOM95 fixed this sometimes.
Next event:
"AMLI: ACPI BIOS is attempting to write to an illegal IO port address (0xcf8), which lies in the 0xcf8 - 0xcff protected address range. This could lead to system instability. Please contact your system vendor for technical assistance."
And immediately after, an attempt to read the address, of course...
I'm looking for a BIOS update for this. Failing that, looking into ACPI and maybe changing some hardware IRQs.
This is annoying.

This is a memory error just try to put your memory speed lower, it depense witch bios your have but am sure it will be more stable. And if you are OVERCLOACKING CPU ... Dont wonder why you got that kind of error. In last resort put every thing to Default Setup Setting and check it out. if you have no problems try enabling things one be one.

i posted a few weeks ago, now after i've reinstalled winxp pro, and upgraded my detonator drivers, now everything is working fine.
im still running my anti virus software (nav2002) and roger wilco has never been installed on my pc....
i think the problem is, at first unstable settings for RAM, Videocard and CPU.
an the second prob, were the nvidia drivers.
i have had the problem with medal of honor ( a blue screen with win32k.sys,while exiting the game ), and i had it on every pc, that was running win xp pro, with a geforce 2 , and detonator 21.xx and 23.xx.
i've read in another forum, nvidia has changed its driver architecture since version 24.xx completly. i think this was the main problem.
get the latest detonators at www.nvidia.com and try it...greetz...

I have the same error message, Page fault in non page area. This has happened 3 times and has comletely shagged my PC. It will not let me boot up even in safe mode, in fact in any mode. It gets to the desktop and crashes. I have XP Pro with geforce 2 400 and amd 1.1 with plenty of ram. I have now gone back to Win Me which is completely stable but unfortunately lacks many XP features.
Looking at the above responses there dosn't seem to be a definate answer but there is quite a lot to go on if I reinstall XP pro so i'll be looking at this page regularly and hoping for an answer.

I had the same problem, and I solved it. The problem is in VIA chipsets:
Also, if you are running two modules I suggest you use bank 1 and 3 because bank 1 & 2 share resources and banks 3 & 4 share resources. By putting them in 1 & 3 they don't have to compete for power and you can tweak the memory a lot more. Moving ram from bank 1 and 2 to 1 and 3 has also elimated the loop error for some people...
This is official info from VIA.
Good luck,
(from RUSSIA)
