Random Shutdowns

I have been working with this particular problem for two weeks now. I am running a socket 1366 I7 processor and Windows 7 Ultimate x64; 12 gigs of ram (for running VM)

I have changed motherboards.
I have changed video cards
I have checked my hard drive
I have upgraded bios
I have tried different settings in the bios
I have tried different versions of video drivers.
I have changed my SATA slots
I have changed power cables
I have changed SATA cables

I was running Vista 64x earlier with no problems on default settings.

I always did clean installs (I have done 5 now)

After changing the motherboard, re-installing, and accepting the default windows 7 drivers for both the motherboard and video card, I reinstalled everything... and after two days of no down time, I thought we were clear.

Tonight, without warning, it reboots (no blue screen, and I went to Control Panel to shut off the "don't reboot" option).

I couldn't get back in windows booting normally, or in safe mode..... it would either reboot on "please wait", or shortly after typing in my password.

I went back to the last successful configuration. I have removed my usb keyboard, and am using PS2. I am working now.

I have removed all references to sleep mode, waking up on lan, USB, etc.

I have looked in the event viewer, and there is nothing that gives me an inkling that anything occurs before Event ID 41.

This last event, I was browsing the internet, had IM on, and a few windows open; no VM.

I am monitoring the heat and power voltage to see if I get any warnings.

The only common denominator between these two motherboards is the same Realtek network card. I have my suspicions here..... my network drives were showing x's (No longer since I have removed the sleep function from the device).

All that is left is the case and power supply. I specifically ordered a PWS with enough power.

I have read several hundred postings on this issue. People 'think' they have a solution, but there is no consistency - other than it happens "randomly".

I even tried the sfc /scannow with no errors.

I seem to remember Vista having issues with sleep functions when it first came out. Possible similarities?

I figure once the big hardware manufacturers start testing their components with Windows 7, they will work directly with Microsoft to document and fix the issue. Otherwise....

This is not a solution obviously, just a list of the types of things I have tried. I will keep posting the group, if my latest solution (no power settings) work.

Additional info:
I was able to look at the system logs, and saw the following Event ID 6, Source FilterManager entries approx 6 seconds before the system shutdown:

File System Filter 'SymEFA' (6.0, ‎2009‎-‎08‎-‎27T21:27:03.000000000Z) has successfully loaded and registered with Filter Manager.

File System Filter 'FileInfo' (6.1, ‎2009‎-‎07‎-‎13T18:34:25.000000000Z) has successfully loaded and registered with Filter Manager.

File System Filter 'eeCtrl' (6.0, ‎2009‎-‎08‎-‎17T18:05:31.000000000Z) has successfully loaded and registered with Filter Manager.

SOMETIMES
File System Filter 'BHDrvx64' (6.1, ‎2009‎-‎09‎-‎11T03:06:53.000000000Z) has successfully loaded and registered with Filter Manager.


SymEFA and BHDrvx64 are Symantec's (Norton Anti-Virus)... so I will see what they have to say.

It's been my experience that random restarts are most often caused by PSU related issues - Either a connection isn't proper somewhere, or the power supply itself has a problem.

If you have access to a spare power supply - a swap would be the easiest way to test.

One thing I didnt see. have you tried testing the RAM? try pulling all but 4 gigs and see result

Just a idea in passing

When I researched error 41, I found there's many reasons for it so it's difficult to narrow down. In my case, the motherboard had blown capacitors on it. So I replaced it and fixed. Since you swapped motherboards already, I agree with the power supply guess by Scotteq. Swap that out for a different one if you can. Or you can also try to slightly increase your RAM voltage and see if it stabilizes like that.

Thanks for everyone's reply.

Yes I had tested the RAM (12Gigs worth)

There was a BIOS Setting for HPET that I changed to 64 Bit (default was 32 bit). That seemed to stabilize it for two days... then today it rebooted when someone across my network attempted to open a file I also had open.

Yes, I replaced the Power Supply today... so we will see how that goes.

The last common denominator is the same type of network card used by both Asus and Gigabyte (Realtek)..... so if the pws doesnt work then next will be using an Intel board with an Intel NIC.

Thanks again everybody.

Hey Guys,

I have the same problem! The only thing I haven't tested/replaced is the PSU, mobo (asus p5q3) and different OS. I will await your findings with the PSU aig! Good luck!

In case anybody is interested, there's a procedure that can be used to conclusively determine whether the "mysterious reboots" are caused by software, and if so what software component is responsible. Otherwise, by a process of elimination the cause is proven to be hardware, though this procedure won't tell you which hardware part is faulty.

To do this you'll need another computer nearby running any flavour of Windows (not 9x though) to "control" the machine with the problem through a serial (RS232) or firewire (1394) cable. Obviously, both machines need to have the same type of port so that a cable can join them together. Then, once the machine with the problem is "controlled" by the other box, you wait for the next instance of an unwanted reboot. If the reboot still happens without the "controller" box being notified, the cause is conclusively a hardware-layer fault. Otherwise, if it's software, the "controller" will be notified of the impending reboot and given a chance to examine the (software) reasons.

It's kinda involved so I won't waste keystrokes and electrons going into detail unless anybody's keen to try it.

 

[ccatlett1984]

I'd be more inclined to consider "dirty" power going into the compter first. I had a issue with a computer rebooting every few days, it ended up being the power at the location, a ups solved the issue.

Are you using the same ram from the previous sysytem? If I were you I would take a very close look at your ram as well. My experiences in the past with random reboots or freeze's with XP were ram related. Depending on your system certain ram can be extremely finicky to achieve stability. I used to have Crucial Ballistix and they were horrible, RMA'd, and no matter what I did I couldn't get the damn things to hold a stable system for more than a few days. Sometimes it would even pass a memtest one day and fail the next.

Even now, with my OCZ Reaper HPC's they are 100% rock solid BUT ONLY after I set a value for EVERY timing in the BIOS, having it on auto was no good for these sticks.

My suggestion run memtest86+ overnight! Let it run through 10-15 cycles of tests. If in the morning it still shows running and no errors, well at least you've ruled out the ram!

problem solved

It appears that the power supply was the offending piece.

After working with a ton of pc's for 20++ years, I have never seen a PS that "didn't work" even though it was providing power.

Why this occurs with Vista and W7 64x machines is puzzling, but I am glad to have my pc back. I have reviewed many posts with this similar problem, so there has to be a communication problem between the os to mboard to PS; I am sure that somebody with greater skills than I have, will solve it someday.

Thanks for everybody's contributions.

It's been about 24 hrs and mine did not reboot yet. what i have changed is where i plug my computer. Rather than plugging it into the power bar with 4-5 other things, it's separate and i have plugged it into the wall directly. I don't know if this will work as my computer has already worked 2 days before a reboot in the past.

thanks for the update aig and others for thoughts and ideas!!

 

[split01]

my pc rebooted!

i will try swapping power supplies...

aig: was there a difference of Watt's between the 2 power supplies?

new power supply

I actually went from a 650 to 700, which I would have thought was overkill, but it certainly solved my current problem.

Hi! I've the same problem with a notebook Acer 5930G, hd and ram test are ok, I've updated all drivers with Driver Genius but nothing...some news?
Thanks and sorry for my english (I'm italian...)

 

[aig]

The answer was power supply

The change of power supply did the trick.... every thing is hunky dory now.

[SOLVED] Kernel power ID 41

Hi everyone, I had the same issue and im running windows7 Ultimate 64bit
I experienced it for few days and I tried many things which have Failed:
I decided to create an account at this forum and share my solution because many people got the same issue as I can see so here is what Ive tried before getting to the final solution;

Tried to:

1. disable on board Audio and network card
2. change the power supply for memmory and everything via Bios
3. disabled the sleepmode and did custom balance power plan
4. updated all the drivers I could
5. tested memmory (no problems were found)
6. tried Safe mode, still got random restarts
7. Tried to disable automatic restarts, also didnt work.
8. Restoring Bios to default settings.

How I solved This: (Gigabyte EX58-UD3R motherboard)

I opened the computer case, and Changed the order of my Memmory Cards.
As im working with 2GB x3
The order at which they were placed inside the slots was Incorrect!
(Note that its a new computer)

So I manually moved them so they all are placed at this order` from Left to Right; and the most right slot remained empty.

means If I have 4 slots and 3 cards, the 4th slot which is the most Right side will remain empty, and the 3 other slots are filled with the cards.
It actually solved all the random restarts, good luck.

Aig, nice. Very glad for you.

I am having the same problem but it does seem to be a problem with the network. The only time it will reboot is if I am transferrring a very large batch of files. 60GB or so. I will drag and drop a number of folders that are quite large and it will always reboot at some point during the transfer. I am thinking it has something to do with the driver that is being used. I will try a different driver and see if it resolves the problem.
