It sounds like something changed the resolution. Turn on the PC, tap F8 a few times and choose VGA mode. Then change the resolution to where you want it.

If the system has always put out a single beep when you power up, and it doesn't do it now, that means your system is dead. That means that you have a hardware problem, and it's usually (but not always) either the power supply or the motherboard. The best guess is the power supply. Do not be misled by the fact that you see some signs of power. The power supply must supply several voltages, and a single one missing or out of tolerance can cause your problem.
