Windows XP

I was have the "Kernel Power Event 41" (no BSOD) issue once to twice a day on a new build with an Intel G620 on ECS H61H2-M3 MB and Kingston HyperX (2x2GB) DDR3@1066. (No over-clocking, used as a Win 7 32bit HTPC)

Under the CPU settings in the bios I had set "Power Technology" to "disable" from the default "Energy Efficient" to correct this.

I'm going to replace the older 300w Allied SL-8320BTX power supply with a ATX v2.3 power supply and re-enable this setting. (Not sure this will help.)

Update: New power supply did not help. Disabling above helped (reset every few days), but also disabling intel turbo boost
I was able to go a week without a reset.

What is the current status of the system? Still running well after disabling turbo boost and resetting power technology and energy efficient settings?

Windows 7 Home Premium 64-bit

Hi again,

It's been a while.
I haven't posted here due to having a huge amount of school work and thankfully not having a restart.

Since my last post I experienced another restart, a little fed up I replaced the CMOS battery with a new one to see if that would change anything.
I haven't had a restart since then. But I'm expecting one.

If I get another restart, I'll make sure to report it here.

Thanks for the help so far,

Nick :)

Unfortunately another restart.
I was about to write this when it restarted again.
So I unplugged the PSU and plugged it back in so it would stop restarting.

Checking the event manager, there isn't something I can find apart from the usual Kernel-Power Event 41. Though, there was an error relating to the shutdown:

- <Event xmlns="">
- <System>
<Provider Name="EventLog" />
<EventID Qualifiers="32768">6008</EventID>
<TimeCreated SystemTime="2012-04-25T05:03:22.000000000Z" />

I might re-install windows sometime soon to try to fix this, I've got too much junk on this install anyway.

I did not see whether you have run the stress tests. If you continue to have problems after doing a fresh re-install, let us know. Clean Reinstall - Factory OEM Windows 7 may be helpful in that regard.

For the hardware checks...
  • If you are overclocking any hardware, please stop.

  • Monitor temperatures during the following tests.
    Use the following programs to monitor the temperatures.
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
    Once these steps have been followed, it is safe to remove and replace components within your computer.
