Strange BIOS signal, what could be the problem?

Question

Iron

Good day.
Actually available:
Motherboard: Gigabyte GA-Z68X-UD3P-B3 (rev. 1.0)
Processor: Intel Core i5 3330
Power supply Chieftec NITRO 85+ Series 750W
RAM: Kingston HyperX DDR3 1600 MHz 4Gb
Separately, everything works, but all together emits a strange signal when loading - first a long beep, then without a pause, two very short ones with a small interval, in general, I don’t know how to explain it better. Can anyone suggest what's wrong?

Answer 1

Reset BIOS to default. You may need to update your bios

Answer 2

1 long and 2 short is a video adapter malfunction.
