Ok so I managed to build my pc for the first time and when I connected it to the monitor I managed to get into the bios and it looked like everything was working. I then tried to manage the cables and put the case back together and I'm having the following problems:

The heatsink fans aren't turning on when they were before

I am getting no loading screen or any signal through to my monitor

And when I turn the computer on with the power button I can't turn it back off

Are their any likely parts I have damaged or should check? All advice is appreciated thanks!
