Windows 7: event 41 lockups help lots of info!

06 Mar 2010   #1

Windows 7 Ultimate x64
event 41 lockups help lots of info! UPDATE!

Ok I'm going to try to present the information i have in the easiest way possible. If you need any more info please ask and I'll do my best to get it to you. I'd also like to add a qick apology for the less than perfect punctuation, I'm typing with on hand due to a recent injury (cut my arm with a grinder) but i try my best still anyway. i can post pics of my arm after the surgery too later if you want haha.

- crashes are consistent in the form of a total lockup. screen remains displaying last image before the crash. rarely accompanied by terrible scratching sounds coming from the speakers which subside momentarily. also rarely accompanied by last second or so sound heard looping.

- uploaded some pictures of a crash with HWmonitor running as well as the sf diagnostic tool dump i made.

What I have done already (I was going to call this "what i know" but i guess i cant really know for sure.

what seems right.

- tested memory with memtest 86+ and sisoft sandra, no crashes or errors
- Tested graphics cards with fur(proper name since forgotten lol) no crashes.
- tested graphics cards with vmt, no errors.
- tested cpu with sandra and a couple other stress tests.
- i think ive eliminated the power supply as the problem by running on only 1 graphics card and 1 stick of ram.

reproducing the problem.

- Run World of warcraft for several hours, crashes randomly with seemingly no set time or cause, however does seem to happen more often on load screens.)
- run unigine heaven benchmark, crashes randomly during benchmarking (never without actually starting the benchmark process even though its already doing all the 3d modelling and such. often freezes on loading screens when i swith settings making it reload.
- has also done it once while burning a movie (during transcoding and not the actual burning process


- no minidump
- no bsod
- stressing individual componants of the system never seems to reproduce the problem.
- switching my graphics cards and ram around seems to solve the problem for a short while.

Thanks for the help guys!

The screenshot shows a system temp of 90 C - awfully hot.
Run the system until it freezes, shut it down and unplug it from the wall.
Open the case and feel around inside (CAREFULLY!!!). You'll be looking for something that's much hotter than the video card is.

The upload doesn't have a copy of the System log file from the Event Viewer.
Please re-download the app (the system log was a recent addition) and rerun it to gather the system log file.

I have the latest version. however it gives me 2 errors

file not found *.dmp
0 file(s) copied
file not found *.dmp

and its at 92 at idle. didnt really notice that. what is sytem temp anyway mobo?

EDIT: okay i felt around but couldnt find anything near the temp of my graphics cards. and sf diag still wont find those files.

EDIT 2: ok ive been doing the 1 graphics card at a time thing and im getting very odd results. last time i used only this card it froze instantly twice in a row, then i switched and it seemed stable. now im using the same card and i cant for the life of me get it to freeze. but i know its not going to stay stable forever. i might rma the motherboard. to eliminate it as a possibility.

.dmp shows BugCheck 124, Probably caused by : hardware those are your clues with no driver named as a bugcheck 124 is hardware fault

as Usasma said your system temp is way too high , ideally it should be below CPU temp so 35-40deg c

I reckon you have some serious airflow problems in your case, just removing the side panel might help a little adding a large domestic fan temporarily to reduce the system temperature might be a good way to see if this is causing the lockup and bluescreen ?

airflow is definitely not the issue. i have an antec 1200 and a zalman 9700 led. i dont know what that system temp is because in the bios it doesnt say anything is near that hot. and nothing feels hotter than my graphics cards. not even close.

ok i just installed xp on a seperate hard drive to eliminate OS issues as a possibility. going to test after updates.

hmm dunno about that with temperatures then scrap that idea

can you run the windows 7 upgrade advisor to check your hardware compatibility ?
