Event ID 41 Task Category 63

[Machinematrix]

Hi, I am experiencing random reboots in my pc, when it happens it will suddenly shutdown, then a few seconds later it turns on again. It has happened playing games and in idle, temperatures are completely normal, voltages on the 12v rail seem normal, I measured it using hwmonitor and most of the time it's 12,1v. Event viewer shows critical event kernel power 41 (63) and this is what i found in event details:

BugcheckCode 0
BugcheckParameter1 0x0
BugcheckParameter2 0x0
BugcheckParameter3 0x0
BugcheckParameter4 0x0
SleepInProgress 0
PowerButtonTimestamp 0
BootAppStatus 0
Checkpoint 0
ConnectedStandbyInProgress false
SystemSleepTransitionsToOn 0
CsEntryScenarioInstanceId 0

It started a few days ago, all instances show event id 41, and in event details "system sleep transitions to on" often varies.

EDIT: A few days ago I could make it happen by tapping the top of the case, so I opened the case and took some cables out and plugged them back in, after that I could no longer turn it off by tapping the case. However a few minutes ago I tried tapping the back of the power supply and it happened again, not only that, but after it turned back on and booted into the system, it happened again but I didn't touch the computer at all. The computer didn't suffer any physical damage as far as I know, and this power supply is around 6 months old.

do you have a spare power supply you could test with?

 

[Machinematrix]

I removed the fan from the older one, it is a cooler master extreme power plus 550w, and I am scared to break something because it is not enough to power this system.

EDIT: I tried tapping the PSU again and nothing happened. Also I forgot to mention that I am not getting any BSOD or BIOS messages. I also noticed that the max temperature was 50C in TMPIN3 (don't know what that is), however I didn't do anything demanding since I opened HWMonitor. The weather has been getting hotter recently, maybe something in the motherboard is overheating.

Cord or psu are crap, replace immediately

It's still under warranty, so I'll see if I can get a new one.

If i get no BSODs, no errors, no events logged in event viewer apart from kernel power 41 (63), not even the windows did not shut down successfully screen (don't know if that is still in windows 10), and the computer just turns off and a few seconds later it turns back on, is it safe to assume that it is the power supply and not the motherboard? Because I have heard that this can be caused by the motherboard. Also when this happens, is it harmful for the rest of the hardware?

This is not always a power related issue, but can be caused by a hardware conflict causing a shutdown that Windows is unable to identify.
Try resetting the BIOS back to stock, and maybe adjusting RAM timings down to 2133, unless XMP profile allows 2400.

I will try that when I get home, thanks. I already disabled XMP and that didn't fix it so the only thing left is resetting the bios.

Often overlooked, but has been an issue for many people since windows 8 and it's easy to try since you just have to uncheck an option and no hardware to test/replace.

If this doesn't work, then it's time to try hardware testing/replacing.

The video is in windows 8, but the control panel for 10 is almost identical.

If you can test it with a voltmeter I wouldn't trust any software to measure voltages of importance

They're not very expensive and you don't use them too often but it's one of those things that's good to have in a drawer somewhere at your house

I will try that.

I could not use my pc these days so I did not have time to test if the problem was solved. I disabled fast startup in windows and no problems so far. I didn't reset the bios so I could know which one of the possible solutions solved the problem.

 

[Machinematrix]

Disabling fast startup didn't work, it keeps restarting, but this time I had the side panel off and I noticed that some motherboards lights did not turn off at all, does this rule out the power supply? also after it turned back on I tapped on the back of the power supply and it restarted again, however after that I tried doing it again several times and nothing happened. This happened while watching you tube videos.
