    2) is the fan going on the power supply

    3) make sure the data cable is connected to the monitor & pc,

It could be a number of things. bad memory, bad motherboard, cpu, , bios bad video adapter etc. as soon as you power up your computer the bios immediately takes control of the computer and performs the p.o.s.t [ power on self test] your computer will play audible beeps. if you write down these you will know the area that needs attention. pay close attention to the number and pattern of beeps and we can get a little closer to solving the problem.
example. 1-1-2 would sound like BEEP<PAUSE>BEEP<PAUSE>BEEP,BEEP.

As you are getting beeps when you try to boot up, that are not in any particular sequence, the problem is not easy to diagnose .
The cheapest solution if are confident in taking the cover off your pc is to

1) if you have more than one stick of ram swap them around & try to boot up,

2) if you only have one stick, replace the ram stick

if this does not fix it ,it is a motherboard or a cpu problem
that can mean big bucks.
good luck with that

Power led light

You need not worry, it appears the LED light is a little faulty and your switch mode power supply is OK.
If you are worried then replace this LED.

Hp compaq dc7600 front panel 3.5 mm jacks not working so no mic and headset and my os in win 7 x32

That can either be a software or hardware problem. Please check BIOS and Sound card drivers to see if the front Headphone and mic jack are enabled. (right click computer ->properties-> device manager) or start programs -> realtek (depending on sound card)

Was it ever working before and do the plug in the back work for your computer?

Computer will not start

It all depends how many beeps there were.
Diagnostic LED Explanation Table Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

I have only really come across 4 beeps = order new Power Supply or 5 Beeps = reseat the memory and hope it works
