I have an ASRock z87, with 1 stick of 8GB ram, GTX 770 GPU, a corsair hx750 PSU and an i5 3.4ghz processor, all of which are connected properly. Every time I boot from replugging my PSU in, it boots shuts off then restarts and does the 3 beeps over an over again. Otherwise just using the power button gives the 3 beeps over and over again with no restart. There is a red light that is constantly on its called BIOS_A_LED1.
I've booted without my GPU, reseated my RAM to each of the slots to no avail. Any ideas?
