Weird black screens?

[patrick1993]

Hi, I recently built a PC, but kidna confused with the result.

I build a PC for a friend, but he has some weird black screens while gaming, but as weird as it sound, if he plays in my house, everything works perfectly. Ieven changed his Mainboard, GPU and recently PSU and yet nothing changed. I still have no problems, but he still does.

I even made the PC to overheat (CPU and GPU about 90 Degrees to see if it could be something about the temperature, but no, I even told him to bring his keyboard, power-, hdmi cable and display itself and again, no problem here, only at his house.

What could be wrong?

Black screens as in the screen goes back and the power goes off, or the some software crash?
