Hello. Recently I decided I needed to upgrade my psu, case, and mobo. Installing all the hardware was not a problem but when I went to boot my computer I got an error on the motherboard, AB (Prepare BBS for Int 19 boot. Init MP tables.). That is what I need help fixing. On top of that, or maybe a part of that I don't know, it says that neither my HDD or the disc the mobo came with is the right drive to boot from. I should also note that the mobo recognizes my ram, hdd and DVD, cpu, and gpu.
