|this is basically not enough information. whats ur motherboard make and model? there are loads if bios beep codes and they vary depending on ur board.|
so tell us ur motherboard and well tell u what that beep means. to start of with this.
make sure everything is seated properly and that everything is receiving power from the power supply. also make sure ur ram and video card is correctly seated.
try testing ur ram in another pc and check if those beeps occur
computers are a second home
