Description of problem
Recently my graphics card (EVGA gtx 780Ti SC) was diagnosed as faulty and replaced with the EVGA 1080 Hybrid. At the same time, cooling paste on the cpu was replaced. An early update to Windows Creators update was also performed (needed that video memory fix). Now a couple of weeks later my pc suffers from seemingly random power losses:
No bsod, no error messages, only a power cut. The pc is immediately able to boot again and works like nothing happened.
To my feeling, it happens the most when using spotify, but it also happens randomly when the pc is running for a long time. The funny thing to me is that it never happens when gaming, which should stress the system the most right? I can game for several straight hours: nothing happens; I open up spotify, 5 minutes in the pc loses power.
Monitoring temps seems to show there is no temperature issue. However the windows logs are filled with a bunch of errors. I tried looking into them but it's hard to distinguish between real issues and service bloat.
Obviously the psu is the main suspect, but I never had any problems with it before. A larger power load due to the extra pump is possible, but I thought the 860 would be sufficient (as the 1080 is also a lot more power efficient). This corsair PSU includes a self test and a led. I have not forced the self test yet, but the led is always green. I will check the cables etc later this week.
Any ideas? Is it dangerous for me to continue to work on this pc? Could it be a faulty application of thermal paste? I kind of need for work.I still have my old 780ti sitting on my desk, I can try swapping it in again.
Thanks for reading and spending time to help people!
When this issue began
After replacing video card (2 months ago).
Cause/Steps to recreate the issue
No specific action is proven to trigger the crash, although I suspect something with the audio connection or the psu. Using spotify is a guarantee to crash sometime soon.
What I've tried so far to resolve the issue
Monitored temps to rule out overheating safety shutdown. I will try clearing cmos this week. Also check if crashes occur with monitor audio output instead of headphones.
Windows 10 64 bit
Intel i7 4790K: idle 32°C
16gb (2x8) Corsair DDR3 1866 (9-10-9-27)
Asus Maximus Hero VII
NZXT Kraken x60
EVGA GTX 1080 HYBRID
Corsair 860i psu = 860 Watt
Asus PB278 (2560x1440p)
Philips Fidelio L1 (6/7 years old)
Cleared cmos (changed ram freq from auto to 1866 tho) and used monitor audio. Power lost 2 hours into spotify.
Trying my Arch partition on the same machine also using spotify. If it's a hardware issue, the problem should persist right?
I can confirm now that no crashes occur when using linux.
