Hello!

A friend and myself have bought new computer parts. But we're having an issue.

When we plug in the 8 pin connector by the CPU, nothing turns on at all, no beeping or anything at all. When we unplug it, everything works fine except nothing will display.

We've made sure everything works too, all the plugs and everything. But once the psu is plugged into the 8 pin connector everything stops working.

I don't get it, someone please help us.

Okay so... you said the computer turns on? But your not getting a display?
what components do you have there? What video cardd, mobo ram and CPU do you have?
