Hi everyone, I'm back again and I've built a new PC. Still having bad luck with computers I guess. System specs are listed on my profile. I've been having problems with my pc restarting, event log shows Event 41 Kernel Power. It happens while playing Dead Space 3 within 5 minutes, but happens during other games occasionally. I thought it was software, until it started happening in my bios within a few seconds. I've tested the ram, switched both sticks, put them in different slots, etc. I've disabled all power saving options and nothing is overclocked. Usually it's random but I can trigger it in the bios and while playing Dead Space 3. I unplugged the reset wire to see if there was a short but it didn't work. This is the same PSU from my last build though, so I'm not sure if that's the problem. There's no way it can be software, right? If it's happening before the OS even loads. I also unplugged my SSD and HDD and still no luck. I'm not sure what else to do except RMA the mobo and/or the PSU.
 
ya it's not software (cause crash in bios)
any other psu 2 try?
any other ram 2 try?
any bios update avaible?
welp it not a easy trouble 2 find gl!!
 
start with testing the machine with a known good psu
 
So no overclock?

Take it to the bare min hardware. No GPU One stick ram, nothing else plunged in. No hot swap bays or anything see if it still does it
 
event 41 kernel power is pretty self explanatory its power related 41 only gets triggered due to a sudden loss of power without tripping a stop code or if the system hard resets without a BSOD

Power related how? I used this psu in my system a few months ago and it was fine, I boxed it up until I built this pc. It's a Corsair ax860 Platinum. If it is related to power, could it be my surge protector? I'm also getting some quirky stuff going on lately. Multiple Directx errors that cause a game crash. I reinstalled my gpu drivers and cleaned them out using driver sweeper, it worked for awhile but I just had another one. I am just not sure if the mobo could cause all of these issues. I tried multiple different combinations with the ram and I don't think that's the problem. The problems started before I even installed the gpu.
 
Do you have Samsung Magician installed?

anytime a system starts freaking out out of the blue the power supply is the first thing to check the fact that its occurring in the bios leads me to believe its the power supply I doubt its the surge protector unless the machine is physically shutting off a bad psu will cause all manner of funky shit
 
I agree with OneMoar if it's happening in the BIOS....
 
the only real way to test it is to either put the psu on a load tester or replace it with another unit its possible its the motherboard or even the cpu its self but anytime you have hard resets like that it means you have a hardware problem and not a software one
I would check everything over for obvious misses like
1. a stand off shorting on the back of the board
2.all wires are firmly seated and both power connectors are connected for both the gpu and main board
3. pull the CPU and reseat it
4. give all the usb/ethernet connectors a look over and make sure the socket's/plugs isn't trashed or something
5.test that psu in another system or test another psu in that system

I have been getting some extremely high temps on my cpu when running prime95 for awhile. intelburntest actually causes shutdowns as well. Temps are good for about 10 minutes and 100% then they skyrocket to over 85

85 is still within safe limits I doubt its directly a cause of your problem make sure the fan control is set to 100% in the bios so its not throttling the pump
I am wondering if whatever issue you are having is making the pump cut out if the pump stops temps will go though the roof in short order if the pump is connected directly the psu ... and that rail is cutting out ...
 
The pc has not reset while running prime95, I do have to kill the program because they will go past 85 easy if i don't.

85c? Again, do you have it over clocked?
 
Is the general consensus that the PSU is defective? It worked in Feb-March, then I boxed it up when I sold that pc to use it until I went sli with 780 ti's. I could just buy one off Amazon and if it doesn't fix the problem I'll just send it back since their return policy is awesome.

did you check everything over and reseat everything like I suggested ?
 
OP, check the Event Log. Right after the 41 shut down, there will be a Debug log; check that and let us know the log code.

Will do tomorrow morning. Thanks for all the replies guys.

Your event shows nothing; it is as OneMoar stated earlier:

event 41 kernel power is pretty self explanatory its power related 41 only gets triggered due to a sudden loss of power without tripping a stop code or if the system hard resets without a BSOD

Or this quote from MS explains the no event info here --> Windows Kernel event ID 41 error "The system has rebooted without cleanly shutting down first" in Windows 8.1, Windows 8, Windows Server 2012 R2, Windows Server 2012, Windows 7, or Windows Server 2008 R2
The kernel power event ID 41 error occurs when the computer is shut down, or it restarts unexpectedly. When a computer that is running Windows starts, a check is performed to determine whether the computer was shut down cleanly. If the computer was not shut down cleanly, a Kernel Power Event 41 message is generated.

An event 41 is used to report that something unexpected happened that prevented Windows from shutting down correctly. There may be insufficient information to explicitly define what happened. To determine what may have happened and to identify a potential resolution, it is important to know what the computer was doing at the time just before the event occurred.

If event 41 is logged because power to the computer was interrupted, consider obtaining an uninterruptible power supply (UPS) such as a battery backup power supply. An underpowered or failing power supply may cause this behavior. For example, if you added RAM or additional devices or hard disks when this problem began, the power supply may cause the problem.

If you are absolutely sure your PSU is good... check all your connections and be sure they are secure and properly placed.
It would probably be best to un-connect and re-connect each one.
Even the header connectors on the MB, power to wall, UPS, surge protector, ... all power connections.
Make sure there are no power connectors laying around getting shorted out, too.
Turn off, if, any OCing.
Reset the BIOS to defaults.
Check for any over heating

Then deal with windows after your are positive there is no hardware problems.
 
Problem solved everyone, it was either the outlet or surge protector causing the shutdowns. I just moved into a new apartment and I haven't had the issue since, switched surge protectors also. Thanks for all the help guys.
 
If your problem does persist, then swap out your ram sticks. I swear to god I had exactly the same problem as you and it was the ram. Even after I tested them for 4 hours, I swapped them out with another kit and no problems to this day.
