Hello.
I'm writing this for a friend.
Recently he changed motherboard, ram and cpu.
He got a new msi z270 gaming plus and a gtx 1050ti.
When he power on the pc, he doesn't get any video output.
He tried changing cable, using another gpu and even trying another monitor.
He tried to remove the CMOS for 10 minutes.
He had to change PSU.
Any idea?

I don't know the new psu but it is a good one for sure.

Thats sure, every fan spins and it was a technician.
For integrated graphics, he tried to plug the vga directly to the mb.

Fan spins.
Led power on.
No error codes from speaker and no debug codes. It just doesn't send signal.
