New PC Build - i5 6600k video dropout

[BRush1]

Good morning,

I'm having issues with my new PC Build, where my monitor will simply go black at seemingly random times. I am not currently running any video card, simply using the CPU onboard video.

On startup, it shows the MSI BIOS access/Boot screen, then windows 10 login. Sometimes, the MSI screen will be flickering a (or multiple) green horizontal stripe(s), and the windows 10 login screen is simply black. I can hear the usual startup noises, and the PC lights/fans etc. all seem to work as normal, but no video. Nothing can be done, and after a number of restarts, everything seems to start up normally.

Other times, the screen may go black while in use. For example, the other night playing hearthstone (with nothing else running in background), my screen would flicker black for 2-3 seconds, then come back. While black, I could still hear the game music, but again, no video. This happened several times in a row, every 30 seconds to minute, sometimes more frequently.

I cannot "force" this problem to reproduce itself on command, and I cannot exactly predict when it will happen.

It seems to be MOST frequent at either startup or wakeup.

Build details:

MSI Krait Gaming Z170A Mobo

Intel i5 6600k

Kingston 8GB RAM (DDR4/2666mhz)

Already updated, and running all current drivers.

Any thoughts? Thanks all in advance.

At this stage, let's make sure you are currently running the latest video drivers for your graphics controller:

HI Allan,

I ran the driver update which you posted last night, and did not fix the issue. For the record, and maybe to assist/cross reference solutions, I've found another thread which sounds to be a very similar issue other users are having:

Thanks

At this stage, I recommend waiting for new graphics driver on https://downloadcenter.intel.com/ Drivers & Software or check on MSI for updates: http://www.msi.com/product/motherboard/support/Z170A-KRAIT-GAMING.html# down-driver MSI Global

Regarding the HD530 video flickering issue. I can create it and eliminate it at will now that I know exactly what is causing the issue. As for why it happens that is for Intel to figure out.

It turns out to be the DDR4 memory speed. The issue will begin intermittently at 2600MHz and gets progressively worse as I increase the speed. At the maximum speed for my kit 3466MHz the screen just vibrates wildly.

I solved it permanently by installing a nvidia GTX 750 graphics card and disabling the HD530 in the BIOS. Now I have triple the video speed and no more flicker issue. On a personal note I do feel cheated by Intel as was I expecting the video to work properly and did not want, or should have had to spend an extra $139 to solve Intel's video issue.

Thanks for the information. I am sure Intel is working hard to get this flickering issue solved as soon as possible.
