Welcome to the forums, newcomer!

Corsair is the brand of the PSU while 650W is the wattage. We will need to know the model of the PSU. How old is the unit in the build? You will need to check and see if the CPU socket has any bent or broken pins.

Also given how you have an i7, you should be able to get display out of the board's display output ports. breadboard the system with only the bare minimum. What slots are the sticks of ram populating?

Might want to list your specs with more detail such as the make and models of the ram, the SSD and the HDD.
