Black screen flash with disappearing of audio 1-2 second. Getting desperate...

[deiviidas]

I am trying to troubleshoot a very annoying problem. We are getting desperate...

What happens: short blackscreen with no audio, after that everything goes back to normal. Does not matter if you're playing video games or not. Happens sometimes even while watching a movie. They happen once a day in a very inconsistent manner.

He has I7-7700k,
MSI Z270 Gaming M6 (previous motherboard was ASUS Z270 MAXIMUS FORMULA with a few bent pins and not working two ram slots),
Kraken X42,
2x8gb ddr4 3000MHz G. Skill RGB ram
Supernova G2 850w power supply,
SSD 128gb,
1TB HDD,
massive ATX case
GTX 1080 inno3D triple fan
+1080p 60hz monitor with HDMI.
We tried switching motherboards, removing video card and using integrated intel hd graphics, reinstalling Nvidia drivers, changing motherboard, reinstalling windows, using computer without installing geforce experience. NOTHING OF THIS HELPED.
The only possible causes in my opinion are - RAM, CPU or power supply? I don't think it can be monitor just because audio disappears as well.
If you know ANYTHING about possible issue, please let us now.

did you reinstall the os for the new board also use hwinfo sensor page and check voltages ,fan speed and temps post a picture of this result here .

I tried undervolting CPU and even decreasing GHz, setting it default - did not help. After changing motherboard - windows were kept the same. Temperatures are fine. the only strange thing is one of the fans show crazy RPM, sometimes even up to 30'000. But it is porbably a bug. I will send a picture in the evening (uk time).

you need to reinstall the os and all new board driver that crazy fan sped is on what parts .

I am sorry, but how can reinstalling windows once again while having a new mother help with this issue? We already did that in the most high end Asus motherboard. It did not change a thing. Also, SSD and HDD are independant from the motherboard. I can swap them with any modern computer and everything should work correctly, especially if GPU is the same.

What do you mean with board driver? Motherboards do not have any drivers unless you're talking about BIOS.

 

[scout_03]

they have chipset driver and lan even the usb controller also sound one since motherboard maker dont us all the same bios settings check this on msi .

Wait, wait. Everything is working correctly. The issue IS THE SAME as before the change in motherboard. It does not matter, chipset drivers are basically identical. Reinstalling OS and all the drivers just because of switching motherboard is just wasting time, especially then EVERYTHING is working well.

Black screen problem had been for a while and switching motherboard and "using wrong drivers" is definitely not the cause of this issue.

As for the crazy RPM:

the bent pins you talk at start up of post where on the cpu also cpu fan have to run to high to cool cpu did he remove the plastic tab under cooler or use new paste with new board with it .

 

[deiviidas]

Intel does not have any pins on the CPU. Only motherboard has.

Yes, he did remove the plastic under Kraken X42. Yes, he used thermal paste on new motherboard.

So let's go back to the issue. There are only CPU, RAM, Monitor and PSU (both of which extremely unlikely) and storage devices SSD and HDD ( I have never heard that SSD or HDD would cause such issue).

 

[deiviidas]

Anyone knows any possible cause of a few second blackscreen?

 

[scout_03]

this gpu did you test it with gpu-z rendering option and use hwinfo to check temp fans speed and voltages in system on the sensor page .

run the intel cpu test. if you bent some pins you may have damaged the cpu (cache) or memory controller. run memtest86 from a usb stick see if the ram is fine.
