Hey there,

apologies if any of this is vague or not informative enough, i'm completely clueless when it comes to computers and anything related. [strike]I also hope this didn't get posted in the wrong forum, i'm obviously new here and signed up just now.[/strike]

Last november i purchased a new computer after my old one has been running faithfully for about 8 years. For about a month it went perfectly; no lags, no shutdowns, worked perfectly well with, say, Skyrim on highest settings and about 30 additional mods (which may not be a relatively demanding thing, i really just don't know). Around christmas eve (i'm not sure about the exact date, which might be relevant to any software updates released around that time) it then began to turn off instantly during gaming. No Bsods, no warnings, no previous lagging, the power simply went off and i then had to wait about half a minute and sometimes even had to unplug it before i was able to reboot it. This didn't happen predictably, but after random times spent gaming or streaming drawings in Paint Tool Sai. Sometimes merely a minute passed, sometimes it worked well for days of almost 10 hours played.

I used to discuss this at length with an acquaintance who knew more than i ever would about computer-reated issues, and of course we first tried to update every driver possible. When this failed me i re-installed everything, only to be met with the same issue again. We ran a bench test (is that what it's called?), which went just fine, although we did notice the GPUs fans didn't work optimally and adjusted them. While the computer wasn't exactly overheated before it certainly wasn't afterwards, but this didn't fix the problem either.
Since at some point around the first time this occured i exchanged an old outlet strip with a new one i assumed this might've been the issue, exchanged it (didn't actually plug any other device into it other than the tower), and...the issue remained. Same goes for using an entirely different outlet in this apartment.
Since its warranty was still valid i sent it back to the company i got it from and they basically did the same thing i did with the same results: it performed really well during bench tests (over an entire weekend afaik), but when i used it after its return it still produced the same issue.
I've been googling this issue and most discussions are almost, but not quite describing the problem at hand. The most common solution seemed to be to get a better PSU, but i didn't expect the 600 Watt EVGA 600W, 80+ i have to be the issue at hand (though, of course i could be mistaken).
Its event ID is always 41 (kernel power error), which doesn't really say much at all.

Anyways, sorry for the lengthy text. Here's some more info on the system.

Thanks a lot for reading this in advance, i'm sorry this got so overly lengthy. Have a good weekend in any case.
 
you have the same motherboard/cpu as me.

can you open Asus suit II and give me a screen shot of your "turbo evo" page, and "sensor recorder" page please. I'm not the biggest fan of Hw info but there is something that stands out to me already that would cause your stability issue.

also can you give me a screen shot of the AMD overdrive "cpu status" screen.

Thanks a lot for your quick reply. Asus suit II won't install (clicked the application button, but other than multiple windows popping up to ask me again if i'd like to run this application nothing happens), but here's the AMD screen.

ok well amd overdrive screen looks normal.

well you would have to look in your bios then to check the cpu voltage but it should be around 1.3625 volts but between 1.3-1.4 as there are slight differences in the the fx chips (hw monitor shows your cpu voltage to be low but amd overdrive shows its as ok but I would check the bios to make sure its ok as low voltage would be #1 suspect in my view of your issues, I normally only trust Asus suit II sensor recorder to actually read the motherboard data correctly but its not working in your case)

your Northbridge and Southbridge should be 1.1000 volts (hw monit is showing your voltage is high)
it is not show but NB 1.8 should be of course 1.8 volts

I'm afraid the computer currently boots too quickly for me to acces the BIOS. I know i've managed to do so in the past, but it's basically going straight to the "Starting Windows" screen these days (will keep on trying tho).
However, there really seems to be something off with the voltage. I've suspected it to be the cause of my issues in some way before already, but what could actually cause the voltage issues themselves? And how would i (with my extremely limited knowledge) fix this?
 
could be the bios settings are off could be other issues. without asus suit or bios access no idea what you actuall settings are. really need one or the other to see whats happening.

sounds like fast boot is enabled without asus suit installed your option is to. shutdown your computer normally then look on the bottom right side of the motherboard by where all the case wires plug into the board is a little black button that says "Directkey" push that button and your pc should power on and boot directly into the bios without you pushing any other key..

Hey, thanks again for your patience. After a bit of searching and troubleshooting i was able to install Asus Suite II. Unfortunately it won't let me change the language settings, so i'm not sure where to look for the turbo evo page. Gonna do it some time later (kinda busy rn). Here's a screenshot of the sensor recorder so far.
Edit: Tried to install Asus TurboV Evo, but according to the error message "this model is not compatible".

Hmm, in that case i really don't know what else could be the issue at hand. Many thanks for looking at this in any case.
(Edit: I'll try to monitor the voltage over the day a bit. According to Asus Suite the core voltage tends to go up quite frequently, but i simply don't know whether this is normal or not. Should probably try to see how it does while gaming, too.)
(Edit II: I'm unfortunately unable to use the computer without an extension cord. Could this be a problem as well?)
 
the core voltage should jump around while system is idle. when running prime 95 or any stress test on the cpu the voltage should not change (const load on cpu. constant voltage) when it is idle it jumps around as the cpu goes into lower power states/lower freq to save power because its just not doing anything.

as for the extension cord as long as it is a good extension cord and it supports more then 10 amps and everything is plugged in well should be an issue.

makes sense. i suppose i'll have to look for another potential cause for this mess.
on another note, the gpu's temperate lately rose to about 60°C while gaming, fans running on max speed and all. i guess that means i'll have to clean them again? or could this be an issue with the thermal paste? i'm sorry for bringing this up randomly, didn't want to start a new thread for this.
edit: [strike]oddly enough i just noticed the computer doesn't shut down on minecraft with shaders and various mods, which struck me as more demanding than some of the games it's shutting down regularly on. really don't know what to do in this situation anymore, this is just making it more confusing to me.[/strike] nope, shut down just now while minecrafting, too (after 5 minutes of gaming, when it's worked perfectly fine for hours during the past few days).
