Hi there,i'd not switched on my computer for 6 mths.when I switched it on it started properly.?
Answers:
Need more info, but the beeps mean different things, like if its one or two or three beeps it depends on the motherboard what the beep means. If you have turned off the power all the way and turned it back on and it starts to boot up but then it beeps that could be a hard drive problem, if you only get a blank black screen usually for me that is the ram not working right.
I believe your computer has fault the bleeps you can hear are a code to aid tracing

post beeping codes
Bad Motherboard - 1 long and 1 short beep
Disk drive related problem / Video card problem - 1 short beep then nothing happens
Bad video card - 1 long and 2 short beeps
Bad power supply - 1) continuous beeps, 2) non-stop short beeps
Bad memory - 3 short beeps
These codes DO vary from one manufacturer to another. Almost all computers list the appropriate codes in the User's manual under technical information or the troubleshooting section, so be sure to check the manual and verify what the codes mean.
If no beeps are heard and no display is on the screen, its most likely the power supply. Check for Keyboard lights or for hard drive/floppy drive lights. If lights come on then power supply is good.
Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function. If you get lights then it could be one of the I/O cards. Try removing each card one at a time and restarting the computer
