I recently purchased a FX 9590 to replace my old Phenom II. I swapped in the CPU, but when I turned on the computer all the fans and LEDs come on, but the screen remains black, no bios or anything. I swapped back to the Phenom and upgraded the BIOS then back but still nothing. I've doubled checked the CPU power cable and pump/fans are connected.
Is my CPU just defective or could there be some other issue?

It turns out I forgot to reset the BIOS to the default settings, everything works fine now.
