PC failing to reboot correctly

Hello TenForums members,

I'm having an issue for a while regarding my PC. Easiest way of explaining is this:

- I press 'Restart' in my start menu
- PC starts restarting
- Screen goes black after done shutting down (FANS&LIGHTS stay on)
- PC stays like this forever till I shut it down with the power button

Today I did a last attempt by formatting, but even when the windows install reboots it gets stuck at black sreen. Even if I restart trough my BIOS it stays on a black screen.

What do you guys recommend?

-- EDIT:
I updated my PC specs, in the meantime i have also changed my SSDrive

When I had a fail to boot problem I did a cmos reset on the mobo.

Have you added anything before this problem started ?

I have been upgrading my computer a lot, in the meantime I changed memory, added a 2nd videocard and watercooling

Did you change the items 1 at a time or all at once ? if you can take out the changes then put them back in 1 area at a time i.e ram change (then test) if ok then 2nd video card ?
