Hearing a beep upon boot up can mean several things. The two most common problems are with the keyboard not being connected or a missing signal from a graphics card. The beep is telling you that something is missing so if the first two items are OK start checking all your connections.
You can assume the video card worked fine.
You can assume the problem is with the monitor, monitor cable, or the video system.
Mine does it a lot, all you need to do is restart it, It doesn't do it often, it's just because it's old.
If its Windows that's normal. It means that Windows has booted with no errors. A blank screen would mean that your monitor is not plugged in correctly to the computer.
The first thing to check after ruling out the cables and the connection to the outlet would be the video card. It could also be the monitor.
Check the monitor or the monitor cable.

The Dell Optiplex 745 can be extremely useful when it's working properly. If your computer starts to boot Windows XP then stops you should try to clean boot it from Safe mode and then go from there.

The video system
it will need to be charged.And then again it might not have to be changed.Have you tried booting in safe mode? It could be as simple as the computer getting hung on start up.
CMOS or BIOS. If you get nothing except a blank screen and never continues sounds like a graphics card
No. The computer would still boot, and you may also hear the fan running. If the screen flickers, is blank, or dim, then you may be suffering from a bad inverter board.

If your screen is blank, check your video card first. Otherwise, this is most likely a hard disk failure if your computer won't boot past BIOS. Also, check to make sure that you don't have anything but the monitor, mouse and keyboard plugged in because this can also cause the computer to freeze at boot. (if the CPU fan fails to spin the computer might not work either) I had the same problem with my HP Pavilion from early 2000 but I just let it sit for a few minutes and it booted up fine. Replace your hard drive/video card as soon as possible.
If a blank page keeps appearing on the computer screen, it is a good possibility that the computer is trying to download a program that the user has not authorized. To get rid of this blank screen, the user should run a virus protection program scan. A system restore can also be used to restore the computer to an earlier time before the blank screen started appearing.
