Event ID 41

[bertie97]

Anyone know anything about what may cause this?
Have random reset occurrences on a laptop with Win7x64.  [Intel i5]
No dumps or error logs written just ID 41 recorded in Event viewers logs.
Time of day; day of month; temperature (ambient or unit); load; type or number of progs running; uptime etc
Nothing seems to make a difference.  Might be twice in 10 minutes or once in 20 days...

Driving me crazy.

Have you tried gradually disabling/uninstalling software/drivers to determine the moment when the problem is gone?

when you say resets, you mean random reboots ?
See if this helps any .

I also found that link.
And also check the BIOS, a broken Power Button don't cause this as this is a restart issues(except you has the BIOS set as start the computer after power fail.).

Thanks for the replies guys.
I have rolled the unit back to factory defaults & gradually tried different software also.  The problem with (most?) laptops is the drivers never seem to see any major upgrades.  You check for updates & it's still the same as it was 6 months ago... I can try a generic driver on some hardware but of course it's not recommended & hasn't changed anything yet either.

I looked at that MS explanation a few times & it doesn't seem to apply, the events occur when the battery is at 100% & it's on AC, started when the unit was about 6 months old so the hardware 'should' be good...
I decided that maybe something was drawing too much power & forcing a reset (rebooting as if I pushed a reset button) but no dice.  Doesn't matter what or how much is running nor how long, so I'm thinking intermittent hardware fault but it's just so random.

It could be hardware related, PS , only thing I can see is check cooling is good and everything is plugged in right, if you can easy get to inside of case .

Did you setup windows so it doesn't automatic reboot on crashes ?

Control panel>system>advanced system settings>startup and recovery>settings>system files , disable automatic restart

Make sure "write an event to the system log" is checked

Maybe there are some short circuit?

And did you remember when it will be restart?
Like typing the keyboards etc.

I went through a period of switching external devices, buying extra cooling & monitoring temps.
Load, temp, devices, what is being done - none of it makes a difference.
It is as random as I can imagine, & I've been looking for common factors quite intensively in logs etc.

I did disable the the 'restart on BSOD' option but I haven't got any results yet.  Investigating logs etc shows nothing, in fact there is an absence of logging & on restart 'missing' folders logged during boot.  Makes me think the HDD is taking a good belt & losing a chunk of data every time.

I think it must be hardware but it hasn't shown itself yet o any diagnostics

Yup, it is hard to find out why, if you don't has the step to make it happen again and again.
