Helping a friend upgrade his PC with a new Gpu and PSU everything was going fine until we went to boot it and no post. Wierd thing is that the Gpu fans start spinning and also the PSU fans spin but the PC wont boot.
The PC we are working on is the NZXT foundation PC.

Make sure you have all of the 8 pin power connectors connected to the GPU and monitor plugged into the GPU rather than motherboard
