Get red LED on motherboard (Asus P8z77-v lx) after new RMA PSU

OCZ PSU's are lower quality so the old one could have done some damage if it failed.
Remove all RAM, power on, listen for beep codes from the Mobo speaker. No RAM and no beeps indicates a Mobo problem.
If you need a new Mobo, Asus & Gigabyte are the better brand choices.
Note: the OS is tied to the present Mobo so replacing it will require a reinstall of the OS.
PC Specs?
Pre- Built Brand & Model Number
Custom Built- Brand & Model of Mobo-CPU-RAM-Graphics-PSU.

Any PC shop will have a Mobo speaker and the Mobo manual will have instructions and/or a pic of where it goes.
My assumption was this is a build that had worked previously and had a failed PSU replaced.
If it's a new build, Hyper X RAM is no stranger to compatibility problems.
What are the specs on the RAM?
