FREEZE: Event ID 41: Kernel Power

[cristoph]

Hi Guys,first of all its great that this forum exists!

I have a problem with my 2yeard old HP pavillion dv966ea. I recently upgraded to windows 7 , and everythingh was good for about 2weeks, now it suddenly crashes and I get the same Kernel Power critical error as some other people mentioned. It crashes randomly, sometimes not in hours...but always when I'm starting a certain 3D client poker software, it freezes and I have to use the power button...after the restart even the HP logo at boot up is sometimes in colours. the only way to get back to normal is to run in safe mode and than restart. that normally seems to do it.

I did a lot of research on that, reading all the related articles on this site as well, so here is what I tried so far.


Clean installed w7 (7600)
tried with or without updates
tried all the drivers on HP website and experimented with Nvidia drivers
updated realtek audio drivers


it would be great to know, if this is software or hardware related.(don't have warranty anymore) I hope anyone can help me with that problem.

btw. computer never crashes with the pre-installed vga-driver, but I can't run the poker software with it. My guess is overheating...but I have no idea what or why?

Thank You and
Best regards
cristoph

Hello and welcome to sevenforums!

I have been running Windows 7 since the alpha days. I am now running the retail version on 4 or 5 computers and one in particular is experiencing the very same issue you are reporting. After searching for information on this event, it is apparent many folks are having this issue. I have read many different ideas how to fix it but none have actually worked. If I find a resolution, I will post it here.

Could definitely be blown capacitors on the motherboard. Check for leaky brown substance coming from them and also for rounded tops instead of flat. It's definitely hardware related. The power is not well to the cpu for whatever reason. Caps regulate power to the cpu, on the motherboard.

Anyhow, also noticed this.

Google these drivers to find out about them and do your best to get them updated to 2009 versions:

thank you fror your answers, good to know that i'm not alone out there with this problem.

it got even worst since my last post, even when i'm installing w7 clean from DVD the screen won't recover and I got flickering. hardware it is then! Not sure if its that easy to replace it..will do some research on that!

thanks for your help!
will check out these drivers as well!!!!

 

[torrentg]

it got even worst since my last post

Very much sounds like a capacitor problem now.

If found to be faulty, they are not too difficult to replace for a hobbyist with the proper wattage soldering iron. If you do replace caps, get low esr type with same specs as original.

On the other hand, motherboards are fairly cheap these days. Unless you enjoy the challenge of the hobby itself, you'd probably be better off just purchasing a replacement board.

If you're interested, you can see about the situation here to help you diagnose.

And from here:

"System Faults:
Motherboard fails to POST.
Memory Test Fails.
System randomly and/or constantly reboots itself.
Fails to fully boot (or even install) Operating System.
System randomly and frequently freezes.
Random & frequent 'Blue Screens of Death'
BSoD or hard freeze under heavy drive activity (Either RAID, SCSI, or standard ATA)
CPU temps abnormally higher than usual under typical or less load.
*CPU VCORE & other system voltages are erratic or far out of tolerances.
Resetting the system after a freeze and the system will not repost.
(You have to completely power down then power back up.)"

Torrentg is very knowledgeable and you should follow his instructions. However, try this first....

I just wanted to let you know I fixed the problem I was having with screen going black, no response from the PC, power reset to get desktop back. Event Id 41 kernel-power critical error in the event log or BSOD possible. Here is what I did to fix it.

My fix was to go to Device Manager, right click on the video adapter and click update device driver, selecting the option to search automatically for a new driver. It found a new driver and installed it. Problem has not returned. The driver it installed was nVidia GeForce 8.16.11.9107 dated 9/27/09, which is before the October push. I hope this helps you.

 

[cristoph]

thanks for the replies!

I really think its a hardware problem and it has def. to do with overheating in some kind of way. either the grafics card or the mobo. i tried avery driver out there a couple of times.

after the last clean install of w7..i know can at least see my screen, although I'm on 800x600 pixles. Because when I tried to change it last time, computer froze and when turned back on..it was like a rainbow, I could hardly see windows..had to guess most of the time where the buttons are.(there wasn't even an option to change the resolution anymore after that happend) that leads me to the grafic card.

and as the grafic card is build into the mobo...and I def. won't be able to repair it..it doesn't look good for this £900 baby!

 

[torrentg]

Graphics cards, even onboard, still use capacitors and now what you're saying, even more sounds like they've failed.

Did you check them out to see?

 

[cristoph]

I was trying to get to my mobo.
But I have to get acces from the top, through the keyboard etc. , which I found very hard with the one screwdriver I have here.I didn't get far in 30min (I'm just renting a room in London at the moment)

I also have next to little experience with repairs..and wouldn't be able to do it myself right now.
I'm also a bit scared to mess something up, I need the computer desperatly atm...and for now it runs at least...even though its on 800x600. (I never thought I would say/write that!)

 

[wguimb]

Update:
I was having that same exact issue and tried updating the nVidia display driver, which made the problem go away fo three days. But, alas, the kernel-power messages came back when the screen went black and locked up the PC.

This time I had the case open and saw what happened. The PSU stoppred, all fans inside came to halt at the same time. Power supply failure. Bingo, time for a new PSU.

 

[cristoph]

mhm...I suspect that the fans have something to do with it, as the computer always broke down when starting a resourcefull application (right now it would even brake down if I chance the resolution)
But i believe my fan is working, at least I can here it.

 

[Epic621]

I'm having the same problem but I don't think that it is hardware related, if your system locks up what do you do? You shut it off and restart it or just hit the reset button. Each time you do this it generates a kernel power event id 41. My computer never did this before windows 7. This is an OS issue, my voltages are well within acceptable limits and I'm not getting any spikes or dips and there are no blown caps on my board or graphics card. My RAM is also clean and passing memtest, no broken leads or unexpected dumps and I have only had 1 BSOD since the install and that was the first time I booted up and driver updates handled that. I'm still stumped on how to fix the problem but I'm pretty confident it isn't my hardware.

 

[cristoph]

is your boot screen damaged as well?

 

[Epic621]

No problems with the boot screen as of yet. Although sometimes it just doesn't start. I think it might just be Driver compatibility issues at this point. even with all of the beta testing 7 has had I think there are still bugs to work out and third party vendors might not have it quite right. XP had some serious issues when it released too, if you remember.

Hi there, I'm new on this forum, but I have the same issue.
Last week I changed the PC. Old one was great, no freeze there (MB ASUS P5P-800VM, CPU Pentium D 820, 2.80GHz, RAM A-Data 400 MHz 2GB)

New one is too bad, now. There is i5 CPU, Gigabye P55-UD3 MB, Corsair RAM (4 GB) and I had 15 critical stops yesterday (EventID 41)

Intel Turbo Boost is disabled right now (i hope that it could helps, but no change).. so today, I will try disable CPU EIST Funstion.. we will se.. but I'm very unhappy with this.

I'm experiencing also Kernel Power 41 freeze. It's not a BSOD, but a total jam. Happens quite randomly, while gaming and something while just surfing internet.

What would be the easiest way to identify the faulty driver or hardware? Some app perhaps? For me, the bug seems to happen like once a day or two. If the PSU is the reason, then how to identify that?

 

[petdroo]

I am having this problem too, it must be a software issue with windows 7x64, it must be imcompatable with some motherboards??

 

[Ergonpandilus]

I solved this error by replacing RAM. One of them was bad and I guess Win7 is a bit more intolerant with bad RAMs. If you have more than one memory module, then test all of them through just in case.

And I recommend you to update your MB BIOS and all the drivers too. When does this error occur? Totally randomly or when the computer is in stress?

 

[kostarae]

I am also having the Event 41 Lockup (no BSOD...just locks up) --- happens to me when quickly opening and closing AVC HD video. Otherwise, HD videos play fine and close properly. Only occurs when playing 1-2 seconds AVC HD videos or quickly closing after opening one. Haven't experienced it any other way so far.

I'm running i5 750, XFX 4770, G.skill 4gb (passed memtest), Corsair 650w PSU
