So I upgraded my CPU and with a cooler upgrade.
I upgraded the power supply from 600W to 700W.

Went and hooked everything up.

All the fans are working fine, no boot errors but the GPU isn't working.
Any ideas?
I'd really not like to take this to a computer shop if I can because all the ones near me closed down or turned into smartphone repair.

It would help if you told us WHAT components you have.

As for the GPU... make sure it has the necessary power cords. That it's hooked up to the monitor properly. That the monitor is set for the right type of cable. That the monitor is plugged in and turned on.

u upgraded everything but the gpu didnt work?? its the most plug and play piece

you knocked shit loose or your cpu may not be supported causing other issues.
did you make sure bios was updated prior to new cpu?

So the cpu power cable was being dislodged by the H-Cooler radiator that I installed.
Its literally in the corner of the board underneath the radiator fan and I actually cant get it to stick solid into the plug.
I can give a small tug on it and it comes loose at the angle its at.

I got it figured out but I dont know what to do with this cooler now, ill figure something out

remove cooler and hook it up properly.
