Windows 7: Event ID: 41 Kernel-Power after returning from sleep mode

Event ID: 41 Kernel-Power after returning from sleep mode

Hello,

This is an issue I've come cross before and it's either tiredness coupled with a drained brain or I'm with stupid at the moment.

I've noticed something quite odd on this new build, and it actually had the same problem with the old build as well. Everything in the new rig is new apart from the GFX cards which are only 5 months old, everything else is new. I put my system into sleep mode and then returned an hour or so later and then it decided restart without any warning...? When it restarted I looked at the Event logs and can see what happened as this coincides with the time the system restarted. I noticed there was a critical problem which resulted in the random restart... The cause of the problem was with sleep mode, for some reason when I returned from sleep there was a power failure, Event 41 is normally associated with either third party drivers and/or a driver issue. There are a number of checks to go through, it's late at the moment and I cannot get my brain around this at 02:26 GMT.

If this has followed to a new rig and the only hardware which isn't brand spanking new is the GFX cards. Considering they are only 5 months old and were purchased brand new I cannot see this is the cause of the problem. Or could it be, they are properly seated in their PCIE slot and locked into position. I checked all the cables are seated correctly and checked the RAM is seated correctly, checked the HDD data cables and power cable are seated correctly. Checked the Power cables for the GFX cards are locked and seated correctly. Checked the PSU cables are all connected and seated correctly.

Everything looks to be fine. Tomorrow I shall run a cold boot and check one by one through the list of start-up and go into sleep mode through each one which is going to take a long time to complete. It's basically untick everything and then restart and then tick and untick one by one and sleep mode and then back on again to see if there is a Kernel-Power error... I did think one thing which could potentially be the source of the problem. GFX drivers... I mean it's happened in the past with both ATI (now AMD) and NVIDIA drivers.

Any suggestions would be very appreciated.


Need Sleep...

It's taken 2 days to astatine the cause of the random restart and I have narrowed it down to one program as the cause of the problem. Granted some people might be using this software and never encounter any problems at all. Which, I can understand, because all computers are unique and no two computers are the same. Therefore, somebody will be running this software and never encounter any problems.

What I have done is a basic logical assessment risk analysis to cancel out variables one by one to determine the cause of the random shut down, my conclusions are correct. O&O Software Defrag 15 causes your system to become very unstable and likely to crash the system and cause to reboot. It is a logical conclusion, as O&O Software Defrag 15 is not installed and there as been no event logs showing Event 41 since.

I have setup a custom event called Troubleshooting Power with the following event source and event level set to:

Event Sources:
Kernel-PnP
Kernel-Power
Power-Troubleshooting

Event Level:
Critical
Warning
Error

There is no sign of Event 41 since I have decided to not install O&O Software Defrag 15, I will be submitting a full analysis report to O&O Software outlining my findings and advise them to look into this software running on Windows 7 x64 and why it's causing Windows 7 to crash. If you are having random shut down and you have this software installed then, there is a possibility it could be the cause of the problem. It is a painstaking task to go through your entire system and it will take a couple of days but I was determine to find the cause of the problem. I mean... troubleshooting is what I do on a daily basis. Even I get stuck myself sometimes, it's a never ending learning curve with computers and I'm learning something new every single day. We all run logical variables to determine a cause of an event. Other people may do it different to others.

What a nightmare and thank god it's over.
