This will be my first post with Bleeping Computer and even though i have seen quite a few topics on the same issue, as none of them resolved my problem and i did not wish to hijacks some's issue or bump an old topic, here i am
Note: i have attached perfmon.zip, SysnativeFileCollectionApp.zip, admin.evtx and system_info.txt in the zip file accompanying this post. Full system parts can also be found at: https://pcpartpicker.com/list/PMfXJV (link needs to be copy/paste in the URL bar - the direct link seems to get a 404)
First, some basics: the build i am currently using has been put together in January 2016 from individual parts (new). OS installed by myself on blank SSD (Windows 10 Enterprise N). The system was stable for the better part of the whole year while i used both as a gaming rig, as well as software developer/work desktop. Some of the games i played at top settings (Rise of the Tomb Raider, Shadow of Mordor, Tom Clancy Siege, Starcraft II, The Witcher 3, Battleborn, Metal Gear Solid V and Battlefield 1 - not a massive gamer just like options ).
My problems first appeared in October around the 22nd and they presented themselves as sudden restarts (or better put shutdown and immediate power up) while gaming. The most specific things i remember about that time was that i installed a new keyboard (K70 RGB Corsair) and the nVidia drivers were updated - can't remember if there was a Windows update and update history is not telling me that far back for some reason.
Now, these restarts were sporadic happening a maximum of 5 times in Siege since then, but more often it happened with Battlefield 1 (at least 1 in a 2 hour session). Because of the infrequency i blamed it on bad drivers and just waited out for nVidia to come up with new stuff. But recently i wanted to try Witcher 3 again (which i did not play since summer when i logged more than 20 hours without issue) and to my surprise the game starts just fine, cinematics are just good, but when actual gameplay starts -> restart. Each and every time like clockwork. Tried new game, different load, installed GOTY version, same thing.
Now since the game worked just fine before October and no issues whatsoever and then the restarts i had with Battlefield 1 this triggered the 'panic' mode and i realized something else might be at fault here. As such i started researching all i could on issues concerning Kernel-power ID 41 with no bugcheck error. More often then not the consensus lied on a hardware fault and before i start RMAing top candidates (right now i'm thinking PSU has the highest chances) I wanted to get an opinion and advice based on what i did so far to troubleshoot - and the fact that i'm at my wits end and don't know how to proceed without starting to each one part at a time until i identify the problem.
So, troubleshooting steps (assume all failed to resolve if no details specified):
- BIOS update to the latest version
- reverted back nVidia drivers to multiple versions since July 2016 (used Display Driver Uninstaller to be sure)
- concentrated on Witcher 3 because this one is the only faithfully replicable scenario and as such tested multiple graphic settings, both the GOTY version and the original version i used during summer
- interesting here was that if i lowered the resolution and ran it in windowed mode it seemed that it was stable (which got me thinking this might be a temp problem - to follow)
- thinking that something happened with the system hardware wise (temp spikes, faulty PSU, faulty CPU etc) i went on a stress test rampage
- IntelBurn on very high - CPU got in the 90 (Celsius) - never did so on any games i ran - nothing happened
- FurMark - ran for more than 5 minutes - GPU went into 72 C stable - all good
- MemTest86 - all 13 tests - 4 passes - no errors
- Still suspecting this might be PSU related, took all the cables apart and put them back together - still no resolution
- disconnected everything from the mobo apart from the CPU and put it back together - nothing
At this point i was calling it quits and was preparing to reinstall Windows (hoping it was a bad driver somewhere), but since I kept having the feeling of a spike happening (more than likely voltage related) i decided to give one last shot, the results of which brought me here cause i really don't know how to interpret this:
- opened my case and disconnected all cases fans (except CPU of course) - lo and behold - the game started working - decent 10 minutes - nothing happened - so i thought, okay one of the fans might be bad. Current fan setup is:
- Noctua on Case Fan Pin1
- Case included fan on Case Fan pin 2
- case fan controller (it's a 3 step button - comes with the case) powered by a molex connector connects all other fans via 2 pin connectors
- so to troubleshoot i start connecting fans one by one. game works until i connect all the molex powered fans - game starts restarting the PC again
- so i take out 2 molex fans and put back the Case Pin fans - still restarts
- take out case fans and go back to molex fans and fidget with them again until i think i have either a faulty cable or faulty fan - so i leave out those parts and start the game with only one case fan working - surprise - game restarts again - which did not happened a few steps ago
- i remove again all the fans just like i did the first time - game still restarts - so my bewilderment grows
- last chance - i remove the entire PERF power cable from the PSU and the game still restarts the PC
At this point i am unsure what to do next except reinstalling Windows and giving it a try on a non-updated non-used system and if that is still a problem, warranty the PSU and keep my fingers crossed.
So, any help would be very appreciated as i think i have exhausted all convenient methods of testing (i have a few friends with similar rigs but since i'm leaving on a business trip on Saturday, it's a bit hard to coordinate exchange of parts to test out the hardware).
