Kernel-Power error Win 7 x64

[Kyle1886]

The situation:

Win. 7 x64 new build during the "burn in period" prior to printer/network/keyboard drivers and others, the PC shut down and restarted several times on it's own. No "blue screen" but the standard "Windows shut down inappropraitely..." Other than system software, I think the only other software installed is Office x64 and Nero 10 although I'm not positive. (I'm not building the unit, but it's all new hardware/software).

In the Event Manager the following error:

Critical Kernel-Power 41 (63)

I've done the usual Net search and it seems to be a common issue with few solutions. I know there are some pretty sharp PC techs here so thanks for any guidence or solutions.

ADD: Another error: "Express Gate incomplete..." This happens when trying to download Windows OS updates. Are they related or separate issues??

Express Gate is a feature on some Asus Motherboards. You should also install all your drivers before you attempt a burn in, since you cannot test devices that are not initialized.

Thanks JDay, finally got the system to run long enough to load the new drivers but the problem exists. (i.e. between 17:23 last night and 18:03 last night there were 9 spontaneous shut down/start ups). We disabled Express Gate as some MS forums suggested, no help there either.

Thanks for your input,

Check the event viewer and you'll see exactly why it has been rebooting (well, the error message). You should also run memtest to check if you have a bad stick of ram. And flash the newest BIOS.

JDay,

The only "error" listed in the Event Viewer is about 45 or 50:

Critical error/Kernel-Power/41/63

The system will run fine in the "safe mode" and "safe mode with networking" although nothing on the "network" works in that mode. I think one of the first things the builder did was flash the bios when things went wonky right at first, but not sure. (Motherboard: Asus P7P55D-E Pro; processor i7-870; Win 7-x64 Pro).

Note: the "builder" is a certified tech that has been in business for over 18 years. He and his employees are stumped, so I really appreciate your feedback.

Respectfully,
Kyle

What parts are in that system, ATI video card by chance?

You could always try another motherboard or some known good RAM too. I'd also run the ASUS motherboard monitoring utility and make sure the voltages are stable and in the right range. You should also run the ASUS Update utility. Both of those can be found on this page.

Then they should have tried the process of elimination already.

Power supply swap, THEN test again. Something of at least decent quality, like a mid-range Antec.

I second the power supply swap. Its a cheap swap to do and might fix the problem.

Also Office x64 isn't even recommended by Microsoft so you should ditch it and install 32-bit. http://technet.microsoft.com/en-us/l.../ee681792.aspx

Basically only install the 64-bit if you need to breech the 2Gb Excel file limit. However, if you have an excel file over 2Gb, you are doing something wrong. That kind of data belongs in a database.

Um, NO!

If users in your organization depend on existing extensions to Office, such as ActiveX controls, third-party add-ins, in-house solutions built on previous versions of Office, or 32-bit versions of programs that interface directly with Office, we recommend that you install 32-bit Office 2010 (the default installation) on computers that are running both 32-bit and 64-bit supported Windows operating systems.

They're saying to use the 32-bit version if you need to use legacy plug-ins and addons. And having the ability to run ActiveX controls in Office is a security nightmare.

If some users in your organization are Excel expert users who work with Excel spreadsheets that are larger than 2 gigabytes (GB), they can install the 64-bit edition of Office 2010. In addition, if you have in-house solution developers, we recommend that those developers have access to the 64-bit edition of Office 2010 so that they can test and update your in-house solutions on the 64-bit edition of Office 2010.

As you can see from this quote they are actually encouraging people to move over to 64-bit, for one thing it is more secure.

Thanks for the replys. I've been using computers since 1984, but as a tool, not an erector set so forgive my layman questions.

If the "Critical Kernel-Power" error is due to a hardware issue, like power supply, motherboard, etc., should not that also take place in the "Safe Mode/Safe Mode with Network as well? Does the Kernel-Power error really indicate a power or electrical/voltage error or is it a response to a "Stop" error from something else unrelated to power per se and is logged as a Kernel-Power error due to being told to shut down? As mentioned earlier, the shutdowns/restarts occurred prior to most of the peripherials and their drivers were added, so I doubt that the "added drivers" are the culprit.

Jday, the video card is a nVidia GForce GT-series 1Mb. I think the 220 but not positive. Audio is just the onboard, no dedicated card.

(I'd like to stick with the x64 version for the more RAM aspect if possible).

Thanks, respectfully, Kyle

What you are saying might make sense in a single user home environment. In a corporate environment, there are usually add-ons to Outlook etc that are business critical. When you go to licensing.microsoft.com it basically says only install the 64-bit if you have to.
