Windows 7: Troubleshooting reqd: Kernel-Power Event ID 41

Troubleshooting reqd: Kernel-Power Event ID 41

Hi All,

I recently purchased a custom built computer by Netplus according to these specifications:

Intel Core 2 Duo E8500
MSI P45 Neo-F
Corsair TWIN2X PC6400 DDR2 4GB KIT CL5 x2 (Total 8GB)
PowerColor ATI 4870 1GB
1Tb Western Digital Caviar GreenPower
Samsung DVD-burner SH-S222L/BEBN
Corsair Powersupply 650W TXEU Black BULK


I've installed Windows 7 Home Premium (legal non RC/RTM verson) as the OS.

Whilst playing COD4 online at 1920x1080 resolution I found that my computer would always bail out from the game catastrophically and I'd be left with a black screen with the only option to push the reset button (CTRL-ALT-DEL DID NOT work). This would happen at random points in the game, not at any particular stage nor after an elapsed time.

Upon investigation into the event viewer, I was surprised to see that for every occurrence of this shutdown there was a corresponding Critical level event generated from Kernel-Power with event ID 41, stating that "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

So I went back to Netplus and they said that I needed extra power, stating that the 500W probably did not provide enough juice to the graphics card. So i ended up buying a Corsair TX850W power supply.

Thinking that the problem was solved I happily installed the power supply, verifying that all connections to the mobo, graphics card, fans, HDs and Optical drives were connected.

I fired up COD4 not expecting anything to go wrong, but indeed I got another complete shutdown, with the same event ID in the event viewer.

I'll be grateful for any help to find out why this may be happening and to suggest possible solutions to the problem.

I've googled but everyone seems to be pointing to an underpowered rig, but this is a brand new 850W Corsair unit.

Even 650 watts is way overkill to run that system. Exchanging the 650 for the 850 only helps you to confirm that there is little chance it has anything to do with a power supply--unless you think both are bad. You were never underpowered.

Check your motherboard for any blown or leaky capacitors with brown substance coming out of them. See that the tops are perfectly flat and not rounded.

Bad capacitors can easily cause error 41 shutdowns and do. So do many other things but this is a likely one.

Since it's new though, you should tell the company that made it for you. Error 41 would most likely pertain to something they should fix.

No, nothing brown or leaky on my motherboard.

The problem is still occurring. Only in games, tho.

I took the voltages on my RAM up, and set manual timings and it seemed to work.
