Question Computer doesn't POST

[dreadprinz]

Hi,
I have an HP 8300 Elite Small Form Factor Desktop Computer, Intel Core i5-3470 3.2GHz Quad-Core, 8GB RAM, 500GB SATA, Windows 10 Pro 64-Bit.

The problem is the computer will not Post and the fans will spin very fast for few seconds then stop. Followed by power light flashing and a series of four short beeps (repeats 5 times). After the beeping stops the power light flashes continuously.

I bought and replaced Power Supply, Ram and battery for the CMOS with no avail. I also tried a different HD, removed, clean and install a processor but the problem still persists. Also, the motherboard components show no physical damage.

What else can I try to solve this issue?

Hi, Try connecting an internal speaker (if header available) and see if any beeps when starting the board with no RAMs.

The computer has an internal speaker installed. All beeps come from this speaker.

If removing all components, but CPU and CPU cooler, and starting the board, are you getting any beeps? Does the CPU fan spin without stopping?

With all other components removed, I still get the same beeps and CPU and Power Supply fans spin and stop before the beeps begin.

What beeps getting (like one long, two short)?

Four short beeps (repeats 5 times) then it stops and the power light blinks.

It could be board, or CPU, if compatible RAMs tested and not working. A local PC shop might help.

Thanks for your help.
Quick note, after reading your last post, I decided to remove the processor and the beep sequence changed to three short beeps. I then tried the CPU and the Rams on another computer and it worked just fine. Seems like the motherboard is the problem.

Beep codes for your system are here: https://support.hp.com/us-en/document/c02222922

4 short beeps indicates a failed BIOS flash.
