I have just upgraded my power supply so I could power my new graphics card. The pc worked fine with the old one.
I put the new power supply in and connected everything into the correct place and when I plug it in and hit the on button it doesn't turn on.
There is a green light on the graphics card but that's it.
No power. No noises no nothing.
If anyone could help that would be great.
