Explanation
Three beeps and a black screen indicate a memory error of some sort. This means that the RAM may not be properly installed or connected to the motherboard. Reseating the RAM means removing each stick and re-inserting it, making sure it clicks into place. This can sometimes solve the problem by ensuring a good contact between the RAM and the motherboard. Replacing the power supply, reattaching the hard drive, or flashing the BIOS are unlikely to fix this issue, since they are not related to the memory error. The power supply provides power to the whole system, the hard drive stores data, and the BIOS is the firmware that controls the boot process. None of these components would cause three beeps and a black screen if they were faulty.
