Problem with new hardware upgrade

[Spoonjarspoon]

Hi guys,

I had an issue with my PC where when I pressed the on button, the fans would spin and the LED's would turn on but all just for a second. The weird part is that it would work every so often. It would take 15-20 minutes of just repeatedly turning it on, and trying again and again and eventually it would turn and work perfectly afterwards.

I ordered a new power supply, installed it, and now my issue is gone! Hooray! However, now when I turn it on, although turning on every time without fail there is no display on either of my two monitors. The fans spin the LEDs light up, but as I said there is no display. I'm really confused because as I said it was working just the previous night (after a few attempts at turning it on)

Hardware:

Corsair 750 bronze modular PSU

Palit Nvidia GEFORCE GTX 650 GPU

AMD A8-6600K 3.6ghz CPU

GIGABYTE GA-F2A55M-HD2 motherboard

Make sure the GPU has the 8 or 6 pin plugged in.

Can you still hear the Windows boot-up sounds in the background?

The GPU is plugged in (6pin) and I don't hear the windows boot sound
