Windows 7: kernel-power event 41 task 63 - pc random reboot

kernel-power event 41 task 63 - pc random reboot

Hi guys, this problem has been driving me crazy for the past month. Built a new pc last month:

i5 2400
Asus P8H61-M-LE USB3
8GB Corsair Vengeance DDR3 RAM
Asus GTX560
Kingston SSD 64GB
320 GB WD Blue
Corsair HX620 PSU

All parts are new except: SSD, HDD, and PSU.

PC would reboot itself randomly and the event viewer says kernel-power event 41 task 63.

My biggest hunch is the PSU because there was one time just after I built the PC, it would not turn on when power button was pressed. MOBO status light was lit. Tried shorting out the actual power pins on the MOBO but still did not turn it on. It would also sometimes turn on then off then on again by itself.

Also whenever I'm in CMOS setup, the various voltages seem to be unstable, it would go up and down by +/- .002 or something like that.

Because of those two points plus the PSU is already used and old (was prev used in a server which ran 24/7) I reckon it's the PSU. But before I go buying a new PSU, I thought I'd get your opinions.

Thanks very much in advance. Sorry if I missed some information or if I sound really nooby. Cheers!

Update: I tested the power supply's outputs using a multimeter and all the voltages were normal.

Update: PC will reboot randomly for about 4-5 times a day and then it will stay stable... then will become unstable again after 24 hrs or so...

Thanks Guys!

Another update:

After reading through various posts regarding kernel-power issues - seems like this is a general error and caused by an underlying error. The other posts recommends looking for all the 'red' errors and post the event id's. So here are all my red errors event id's. Thanks guys:

In order of most errors:

CRITICAL:
41 - kernel-power

ERROR/APPLICATION:
4107
10
3011
3012

ERROR/SYSTEM:
2
3
7
10
354
1002
6008
7011
7023
12291

Hope these make sense guys. Thanks!

For the application errors:

Event ID 10 is logged in the Application log after you install Service Pack 1 for Windows 7 or Windows Server 2008 R2

Event ID 4107 or Event ID 11 is logged in the Application log in Windows and in Windows Server


The 41 - kernel-power error just means that Windows shut down unexpectedly. It is an inidcator of any number of things, but the most common are hardware related. Run some 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).

    warning   Warning
    Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!


    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. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Good plan. Let us know the results of the diagnostics as you do them.
