Windows 7: Random restarts. No BSOD. Event viewer error code 41.

25 Dec 2013   #1

Windows 7 Ultimate x64
Random restarts. No BSOD. Event viewer error code 41.

Rather vague title I apologize.

Operating System
Windows 7 Ultimate 64-bit SP1
Intel Core i7 Extreme 965 @ 3.20GHz 46 C
Bloomfield 45nm Technology
16.0GB Single-Channel DDR3 @ 530MHz (7-7-7-20)
EVGA EVGA X58 3x SLI Classified 3 (Socket 423) 29 C
Dell 3008WFP(Digital) ([email protected])
2047MB NVIDIA GeForce GTX 660 Ti (EVGA) 50 C
931GB Western Digital WDC WD10 01FALS-00K1B0 SCSI Disk Device (SATA) 35 C
447GB Corsair Force GS SCSI Disk Device (SSD) 34 C
Optical Drives
motorola XT926 USB Device
High Definition Audio Device
CORSAIR HX Series CMPSU-1000HX 1000W ATX12V 2.2 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS Certified Modular Active PFC Compatible with Core i7 Power Supply

This is with current idle temps. I get random restarts with no minidump and just an error code 41. The restarts can happen After a long period of time (8+ hours idle), or just shortly after running a video game (APB:R forces a restart within 10 minutes)

Drivers are updated, I have scoured forums and past solutions over the course of about 2 weeks. Advanced System Settings option to automatically reset has been turned off. NVIDIA Control Panel's global setting has been set to Maximum performance. My RAM is only two days old. I have an aftermarket CPU water cooling system installed.

I have run several temp logs in games that I would suspect force a restart and checked the time on the restarts. On restart I have not noticed any abnormally high system temperatures. CPU caps at about 62C.

I can only imagine that either my relatively new MOBO is having issues, or the old PSU(from 2009) is the problem. I would greatly appreciate some feedback and I would gladly provide any further information.

Nothing on my system is overclocked, it is all default settings.

If you have not already done so; try running a sfc /scannow and or a chkdsk /f via a elevated command prompt(run as administrator) to see if there are any errors and if there are; whether or not they can be fixed.

SFC found no problems. CHKDSK is gonna run on the next reset. I just moved my video card around to give my north bridge some more air. The inside of my PC is pretty clean and rather dust free stave for some stuff on the bottom. Dust is never really an issues since the PC is not kept on the ground but on my desk.

I ran a game for about 10 minutes to try and get a reset going and noticed my CPU didn't even reach 60C, but my GPU hit about 72C then reset. Sadly my gfx card only has one fan on it. I found a spare case fn and tried installing that under the GPU. to try and mitigate any heating issues but we shall see.

So it seems that moving the Video card away from the north bridge fixed the issue.
