I just built a new PC with these parts:
- Z170XP-SLI (bios upgraded to F6, optimal defaults, no overclock)
- i5 6600K
- Corsair Vengeance DDR4 memory 2 x 8gb
- SSD Sandisk 480 Gb (AHCI)
- 1000W PSU (novatech)
- no discrete GPU, using the integrated one
The problem is very strange: the system boots up, goes past POST phase and the OS installation starts (I tried Win 10 and Ubuntu 16.04 and the behaviour is the same) and after about 10 seconds of showing the OS initial logo, when the screen is about to change resolution (I guess), the system powers off and on again, and reboots.
I am booting from USB stick, no optical drive.. I have an usb keyboard and no mouse.
But the most important information is that if I install a dedicated GPU and connect the monitor to it, all works fine.. I am able to install windows and use the PC normally.. so the problem seems related to the integrated GPU, somehow.
Any ideas?
Thank you very much!
