have you tried connecting the tower to a different monitor?
have you tried connecting the monitor to a different tower?

perhaps your graphics card burned out. hard to say without you doing tests to rule out possibilities.

First and simplest, check the keyboard to make sure no keys are pushed in. Replace it to be sure. Reseat the RAM, check if the fans are blowing. You did not list any computer specs, but check the motherboard for any damage, especially popped capacitors.

The CPU could also have gone bad (too much heat maybe). Solid beeping is usually RAM, motherboard or CPU outside of an issue with the keyboard.
