Computer Black screening and restarting

[redeyedskink]

Hi Everyone,

I've followed threads for quite some time and wanted to post something.

I made my own computer about 2 years ago or maybe a little less.
After having it for about 6 months, I started to have weird issues with my pc which would cause my pc to black screen and just restart all of a sudden.

I've ran stress tests on the memory, I've ran test on my GPU such as benchmarks (heaven) and I've also tested my cpu. There is no overheating that I can see, and no issues with my hardware.

This issue has started to happen more and more now. I'm leaning towards it being a GPU issue but I just can't be sure.

Any advice would be great, but I feel like I've tested everything pretty well.

Under event viewer, I'm getting a kernal power 41 message (which just tells me the power shut down unexpectedly) and event log 6008 with no further information.

Update:
I just ran furmark again and monitored all my stuff. Here are some results:
Average FPS- 43
Max temp- 77
CPU max temps- 35 (must be a faulty sensor) Bios states the cpu is at 25c

Hope this helps a little bit. Any help is appreciated

Here are my specs:
windows 10
i5-6600k
gtx 960 gpu
z170 gaming 5 motherboard
550w seasonic
2x8 gb 2200 ram
1x240 ssd
1x 1tb 7200 HDD

Here are some results from the onboard test for voltage and CPU:

Take a look at the above IMGUR pics and let me know if this is normal please

my result where more linear then these so let see if someone that use similar intel cpu or psu could give us info .

I have a new PSU otw that I ordered. I'll give you an update if this is what it was. I went with a seasonic 650w gold plus. If anyone has any further recommendations based off of what's happening, I'd be happy to hear!

So I managed to manually switch my voltage to 1.10 instead of auto. Using HW and OCCT, I can see that my vcore is now where it's supposed to be (1.10) and is working fine. I'll keep this thread open for now until I can test my computer out some more in order to see if my pc black screens and restarts again.

Thank you for the help!

ok let us know if this solve the issue .

Ok, so I put the new PSU in and it looks like the VCore isn't changing nearly as much now. Here are a couple pics for comparison

I'm going to say it was a PSU issue and call it a day. Thank you for the help!
