Windows 7: Windows 7 64 Bit System Power loss from Kernel – power ID 41 (63)

Windows 7 Pro 64 Bit
Windows 7 64 Bit System Power loss from Kernel – power ID 41 (63)

Within the first five mins of any game or using Netflix, my computer will lose all power. The system does not freeze; the power just goes out like a light. I cannot power my system back on after that point unless I turn the switch from the power supply itself off and then back on, and then I can power my system back on. When I get back into windows I check the event log and it shows it was a Kernel- power ID 41 (63). I have been searching all over the web to find an answer to this issue and so far the only answers I can find are from posts over a year ago which talk about older versions of windows and hardware. The CPU and Video card’s over clocking is turned off.
This system was built on 11/18/2011

· I have done a clean reinstall
· It is a new system so there is very little amount of programs on the hard drive.
· It is odd that in safe mode I can watch Netflix but running windows it normal will cause the crash.
· I cannot test the games in safe mode so no help there.

Windows 7 Pro 64 Bit

  • I did a clean reinstall of windows 7 64 bit
  • Made sure all drivers were up to date, including the video card driver.
  • No AVG or anything instilled
  • CPU and Video card are not over clocked
  • Ran SFC/Scannow command: No issues were found
  • Ran Disk Clean up: everything is clean and no issues found
  • Checked PSU by using it in a different system : No issues found
  • Ran Check disk: No issues found
  • Check all temp: NO heating issues found
  • I switched the Geforce GTX 560 with a different card and I had no crashes with any programs on the new system.
  • I put the GeForce GTX 560 in a Windows XP 32 bit system and it worked great had no issues with crashes at all.
  • I am being to think it is a issue with A. windows 7 or B. issue with windows 7 64 bit. So I am not sure where to go with this. Correct me if I am wrong; a windows 32 bit system can only use a max of 3GB of RAM even if you have more in your system. So since I have 8GB of ram I would need to use a windows 64 bit OS. Am I correct?

Win 7 Ultimate 64-bit. SP1.

While the maximum RAM limit for 32-bit Windows 7 editions is 4GB, when it comes to the 64-bit editions, the amount of memory that the OS can address depends on which edition you are running.

Here are the upper RAM limits for the different editions of Windows 7:

Starter: 8GB
Home Basic: 8GB
Home Premium: 16GB
Professional: 192GB
Enterprise: 192GB
Ultimate: 192GB

Windows 7 Pro 64 Bit

I am running Windows 7 Professional 64 bit so I should be fine with my 8GB RAM.
I tired the GeForce GTX 560 in a windows XP 32 bit and I had no issues of anything kind.
In the windows 7 pro 64 bit is giving me the issue I started this topic on. The card has the newest update software and drivers so I am not sure what to do from here.
If I was only running 4GB of RAM I would have stayed with windows XP 32 bit OS since I have no issues but having the 8GB of RAM is part of the main reason I build the new system.

Windows 7 Pro-x64

Checked PSU by using it in a different system : No issues found
Did this other system have the same configuration?
What make and model is the PSU?

Sounds like your PSU is trying to save itself from a meltdown. Check all the connectors to be sure none are shorting inside the case and that your motherboard AND CPU power connectors are tight. Some PSU connectors fit loose or the pins might eject themselves.

Windows 7 Enterprise 32-bit

**************I THINK I MAY HAVE FOUND A SOLUTION!****************
I got some help from another user on a different forum.

She told me to check my audio drivers. I had three, TWO ATI High def audio drivers and one VIA High def audio

My conclusion is that the two ATI's were fighting echother for the information causing the crash, I disabled one and it works PERFECTLY(thus far) game used to crash sometimes at loading, 10 seconds into game play no more then 20 seconds.. I've been playing for about 3 hours now on all high settings, changin the resolution a couple times a minute trying to cause the crash. I'm unable to cause the crash.


Everyone note this is possibly and hopefully a solution.
