TH7II-Raid no boot problem

[Gaiares]

Need some help with this problem I'm having. My computer has been running fine for the past few months. Well yesterday I turned it on and I hear loud alternating quick beeps repeating. I checked the POST code on the board and it was coming up with error code F5. Took out all the ram and put them back in 1 by 1 and same thing. Started unplugging the power from the components inside and the POST code changed to 00, but same beeping. Right now I've taken everything out of the computer, at one point I took the processor out, but I still get the same beeping. I'm at a loss right now. Hoping it's not the board or the processor. But I'm thinking it's one of the two. Please LMK if you have any suggestions. TIA!

Here's my setup for reference:
