So, I just built my PC, and whenever I turn it on, it immediately gets red + yellow lights on (both same time), and stays so. Tried waiting, tried reseating RAM/CPU, tried flashing bios (not sure if worked, but probably: light flashed -> PC spun up -> after 5 min or so rebooted and light no longer flashed).

Not sure what to do at this point, any ideas?
