PC loses power - Kernel-Power Event ID 41

Hi all

I am not really sure if this is the right place to post this but I couldn't really find any other categories other than BSOD that seemed relevant so if there is a better place please tell me and I will post it there.

I have had this issue for around a year now and I have nearly given up trying to solve it so I would really appreciate if anyone can help me or point me in the right direction.

I am not suffering from BSOD, the actual issue is the computer just loses power, no warning, just instantly turns off. Everything else is fine, things run great, there are no other issues with the computer.

It seems to be random and there is no pattern I can find... It happens sometimes once per day, once per week, the circumstances it has happened under are:

• When is the computer is IDLE, nothing running.
• Computer under load, gaming, browsing, all that general use stuff.
• Nothing else turns off, monitors are fine, speakers are fine they just display the "no signal" error.

I have tried the following:

• Replacing the PSU
• Reinstalling / trying different OS (Windows 7, 8.1 and 10)
• Buying a UPS in case it was something to do with my house's electrics
• Made sure all temperatures are within safe limits
• All components run at stock settings, no over clocks.

My system specs are linked to my profile so please look there.

The only thing I can find in the event log is this kernal power log and honestly I don't really understand what much of it means.

The most relevant link I could find is here:
faststartup issues Kernel power, boot, and unexpected shutdown errors, - Microsoft Community

It seems to have to do with fast booting. One person posts he fixed it by just deleting the prefetch files. Do you have fast booting enabled?

I had the same thing....and boy did it burn me up. But.....even though I was running 8.1, Pro and properly tweaked and tuned for most efficient operation, the shutdowns continued. And like you said, it was intermittent.

The problem turned out to be in the motherboard itself. I won't go into all the gory details, but it was a motherboard that was almost ten years old, and had been repaired several times.

A new Motherboard, CPU, & RAM solved the problem. I'm still using the same Video Card and HD on the new board as I did on the old board, with NO problems.

Carefully examine your motherboard, for any signs of either dirt buildup or bulging capacitors. Even dirty RAM sticks can cause a shutdown.
I've saved many sticks of ram, that tested BAD with Memtest86+, but they were just dirty. So I washed them.

On the really weird side, a bad keyboard or mouse can also cause the PC to abruptly shut down. I've not seen that often, but it does happen.
So if you can, at least temporarily, swap out your mouse and keyboard, just for troubleshooting purposes.

Good Luck, and if you find the problem, please come back and let us know.

Cheers mates!

On the hardware side I did have some issues on a couple of HP desktop machines with Pentium 4 CPUs. Turns out the set up guy didn't adjust the fan speed-up threshold properly. They were both set for the fans to bump up the speed like one degree before the CPU issued a Halt instruction in self-preservation. I found an "easter egg" entry into the BIOS settings where I could adjust the fan thresholds. Could be some weirdo thing like that I suppose. Have you cleaned out the dust in the boxes lately? Checked fan speeds?

Guys

Thanks for your replies I really appreciate it.

MilesAhead - I have taken the advice you linked and deleted the pre-fetch and disabled fast boot. Haven't had any problems in the past 24 hours but as I said it can go a week without occurring

Yes fan speeds are all good, system temps are all in the clear. Its a water cooling block and the CPU doesn't go over 60 degrees even under max load.

I generally clean the computer monthly so it should be fairly clear. The case has dust filters which do a great job of catching a lot of dust before it gets into the computer.

TechnoMage - Thanks... I fear you could be right... I hope not I was hoping the board and CPU would see me through for at least another 2 years or so. Replacing the Motherboard, cpu and RAM is my last resort.

I will take a close look at the board when I get a chance and let you know... I never thought to check.

Funnily enough... My keyboard has caused problems in the past. For example, even now I can't lock the computer. If I do the keyboard infinitely spams a single key until the computer is rebooted or until it's unplugged and plugged back in. It's a razer black widow, great keyboard.. terrible software/drivers.

Before I do anything else I'll see if it crashes now fastboot is disabled then I'll try swapping the keyboard and inspecting the board.

Thanks

Click to expand...

Sounds like a good plan. For some reason IBM PC always had weird keyboard dependencies. The old 286s actually used the keyboard controller to switch into protected mode iirc. Plus the thing would not boot if the keyboard wasn't hooked up. There are probably still weird hardware dependencies in the new machines.

Hi guys

Happened again.

Starting to think I just need to replace the motherboard... Yay.

Thanks for all your help though much appreciated.

Sam

Replace the small things first maybe? Ram.

but then again it's more fun to just get a new motherboard with new ram..


And when you do buy a new motherboard, some of them are pretty cheap by the way, read the forums of the motherboards first before you buy it... and notice all the people having problems before you buy that motherboard!

There are so many sites out there that run tests on all the motherboards.. so look at those too..

Let us know the resolution when you fix it for sure.
