4 beeps indicates ram or video issues.
Try reseating the ram modules and checking the video card (or try a video card if you are currently using the onboard video)

Computer shut down and red light flashing five times then three second pause and repeats


According to the troubleshooting guide for this model, the red light flashing five times indicates a problem in the RAM (memory), before the video subsystem is ready. You may just need to open the case and make sure the memory sticks are fully locked in their slots. If you just added new memory, it might not match the required specs.

Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause Pre-video memory error.

Solution
1.
Reseat DIMMs. Power on the system.

2. Replace DIMMs one at a time to isolate the faulty module.

3. Replace third-party memory with HP memory.
4. Replace the system board.

Hp compaq dc 7100 , my problem is that as i start my pc than 4 beep with time interval 0.2 sec with led than after 0.5 sec it start again , remain continously


Are they Long Beeps? Does the RED led light on the front show up?
If there is no RED led light blinking, then the problem is your RAM.
If there IS a RED led Light showing up, then the problem is your Power Supply.

HP COMPAQ D530 RED BLINKING LIGHT WITH BEEPING SOUNDS.


4 beeps & 4 flashes mean problem with the power supply. For my experience, most of the time the PSU is good, it is just overloaded.

it all depends on the number of flashes , pause, repeat.
Since the problem did not indicate any beeps her is the following info


Power LED blinks RED 2 times, one every second, followed by a
2-second pause. = Processor Thermal Protection Activated


3 blinks 1 second apart = Processor not installed (not an indicator for a bad processor).

4 blinks 1 second apart .= Power Failure (power supply is overloaded)

Other possibilities are:
5 blinks 1 second apart No memory
6 blinks 1 second apart No graphics
7 blinks 1 second apart System board failure (detected prior to video)
8 blinks 1 second apart Invalid ROM
