So I upgraded my motherboard, CPU and ram today and now it wont boot to screen and my GPU fans are not spinning whenever I'm starting the pc (my GPU is a GTX 970 STRIX 4gb) even when the LED that indicates that it has power is on. All LED's on the mobo are on and the CPU fan and the other case fans are spinning and working fine but nothing comes up on my screen. Ive tested to start my PC with 1 ram stick, taking out the GPU and putting in the screen cables into the mobo and it's still not working, tho I have a pretty old PSU which can be the case, but I'm not ready to buy a new one if it is the problem before I've got a confirmation from you professionals out there. The PSU is
Cooler Master M2 Silent Pro @ 720w
I went from this:
MB: ASUSTek P8Z77-V LX 1155
CPU: i5 2500k 3.30ghz
