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.

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.
