So my problem is , that recently my PC screen goes randomly black for 2 seconds. The PC wont shut down or anything. I will see the screen again in 2 seconds. When it comes back, i see HDMI icon in left side of the corner. I thought that i have false connection with HDMI, but it still keeps happening. It started 2 weeks ago.
 
try the monitor on another computer to see if it still happens as it sounds like monitor issue. it sounds like the power board in the monitor is going bad with possible domed or leaking capacitor. it can be fixed as I do that all the time.
 
hmm i will try my monitor on laptop and see if it works. But i heard feedback from my friend, when i stream , they can also see when my screen goes black for 2 seconds. I thought that only I see it, so i think it cant be monitor problem. Must be graphics card or smth. I want to know if i have to bring my PC to support and let them repair it or i can fix it myself.
 
I tried my monitor out with my laptop and no black screen came, even with gaming for 30 mins. So i think the problem is in PC itself not monitor. Any ideas, what it would be?
 
dont know what u realy mean, but i have only one video card, GTX 970, which i bought 3 months ago. Bought all PC 3 months ago

EDIT: oh u mean to use Intel HD graphics and then see if black screen comes??
