Hi, Sometimes my computer shuts down and reboots. I have the kernel power event 41 error message. It is very frustrating. I have not been able to pinpoint any factor causing this problem. A quick Google search has not yet given any significant clue. It is a known problem which is described in the microsoft windows 7 forum but as to be expected the MS solutions are useless. Has anybody experienced that?Thank you

Have you tried asking this on Seven Forums? http://www.sevenforums.com/ I'm pretty sure that you'll get an answer from some of the members plodding around there, but you may need more info on your system & what's happening etc to get advice. Sam.

hi.Thank youThere are hundreds of posts about this problem on the internet. I am afraid it is hopeless. The majority of threads reaches the conclusion that it is windows 7 related and that Microsoft has done nothing to fix this issue since 7 was released. No one has found a solution yet. I even read a post written by a guy who has been a computer technician for 35 years and who has spent nearly a hundred hours on it ,even with the help of dedicated debugging hardware, to no avail. He said that in his carreer, it is the first time that he has not been able to find a workaround for computer problem.The best OS that MS designed is XP, no doubt about it. I don't care about all the useless gadgets that come with 7 , I would have liked a bug free OS instead.

You could try a new PSU or make sure that your PSU is big enough to handle your current system. Also I had this happen once and it happened the exact same day I upgraded the drivers for my GTX 480. It happened once again two months latter. After that I installed the GTX 480 drivers that I was using before it happened the first time. It has been 4 months since I put the old drivers back in and it still has not happened again.

Have you tried a System Restore to the last known good working copy of the OS? Worked for me after much frustration, troubleshooting, and innumerable conflicting hints and tips across the internet. Even though the diagnostics were reporting all OS files present and intact, something had been corrupted in a subtle way and the restore did the trick.

Hi.I have the same Kernel Power Event 41 for 2 months now and at first I thought that I have resolved it.In June I've updated my video driver with 11.6 and after that the show started,3 times a day system restart all of a sudden.At first I didn't realize that the driver was the problem,I've checked step by step the PSU,RAM,voltages...no luck.After a week I think it crossed my mind to check for a hotfix for the ATI video driver and after I installed it no freezes or restarts...until today .Why all of a sudden my desktop froze while I was just listening to music and browsing Avsim library?(after a clean month with no problem).System restore doesn't work for me,the drivers are the same,the voltages are in Auto.

hi, Based on what I've read the problem can occur on any computer, PC or laptop, with any video card ATI or Nvidia, in fact with any configuration. The only common factor W7. Nothing fixes the issue. No solution given by MS (would you believe it?)I wish I stayed with XP

No solutions given by MS?? Google says differently - http://support.microsoft.com/kb/2028504 . I saw where you stated in your OP that MS solutions are useless but they evidently fixed the problem for most people. I would recommend you take your system to a computer repair shop and have them diagnose and fix your problem. You can also reformat your HD and reinstall XP too. I know it's frustrating when your computer stops working the way you think it should but it shuts down for good reason. There's could be an overclocking problem, maybe a bolt or screw laying on the MB, it's overheating, memory voltages are set too high/low, video or sound cards or memory drams not propperly seated. There are so many possibilities. We are here to try to help you with your problem but you don't seem to want to take anyones advice and instead just blame Windows 7. Windows 7 did what it was suppose to do. It told you of a problem with your computer by making an Event. It is shutting down immediately when it finds a problem so that your system will not be completely destroyed. I don't know what else it can do for you but I hope you can find a fix, either through your own investigations or by a computer repair shop. Best regards,Jim

Hi It is not because they talk about a problem that they give a solution. I did what was suggested and was able to find an error message. Basically it told me that the computer had shut down. Thank you MS, that is exactly what I saw. So far you are right. Next it gave me a check code 59 which I had to convert in hexa. If I remember rightly, we are in 2011 and it reminds me of the days when I programmed a 1802 CPU in hexa but that was in 1982. Thank you MS for this refresher course. Well with my 3B I was able to find out that the error was a "system service exception". I must be a stupid person because I don't know what this means, though it is probably very clear to everybody. So now I am stuck there. I gathered that it could be related to a hardware device problem or its associated driver. Which one ? mystery. that is what I call a useful tip. Any idea? See the error message attached.Thank you

Now we are starting to get somewhere. I found a similar situation through a Google search - http://www.ocztechnologyforum.com/forum/showthread.php?72362-Win7-64-Sleep-problems and it turned out to be the drivers for the SSD/HD. I don't know exactly what's in your system. It could be the hard disk drivers are at fault as indicated in the link I provided. You must have received a Blue Screen crash too. If you did, you need to download the freeware Blue Screen Viewer (Google) and see exactly what file caused the crash. You can then Google that file and see what fixes are available on the Internet. Hope this helps! Best regards,Jim

hi,I was away for a couple of weeks so I could not reply to your post. No I don't have a blue screen. I don't have an SSD. It just shuts down and restarts immediately. It is difficult to investigate because it happens randomly.Thank you for helping me.

I assume that it is not a FSX issue but an W7 one? I cannot read what you have under the hood so..start here

hi, the tool looks appealing..... but it just confirms what I already saw... . In my case it is useless, unfortunately It is funny that MS designed a software which gives you an error message that says that the computer was shut down . I can't imagine a case when the computer shuts down and the user can't see it. Thank you for the link though because it could be useful in other cases
