Hi,
I am currently trying to fix my HP pavilion a000 desktop. I was working fine then after turning it off i tried to start it again and it just beeps at me.

I have tried cleaning all the fans and dust of all components but its doesn't help.
I have checked the memory and cd/dvd rom but it continues to beep at me

Is this a case of getting a new tower or can it be fixed?

Building on the thread (notably comments from , and ), here is a compact, practical diagnostic sequence for an HP Pavilion a000 that emits POST beeps. The aim is to isolate the failing subsystem without needless parts purchases.

A simple, ordered checklist:

  1. Capture the beep pattern precisely: count long vs short beeps, note repeats and pauses (record with a phone). The pattern narrows the fault once the BIOS/vendor is identified.
  2. Verify the system speaker is present (some HP machines mute a chassis speaker); if no internal buzzer is fitted, an external PC speaker is useful.
  3. Minimal-boot test: power off and unplug, open the case, remove all non-essential cards and drives. Leave CPU, one RAM stick (try each stick individually in the primary slot), and PSU connected. Boot and observe. If it POSTs, add components back one at a time to find the culprit.
  4. Reseat and recheck connectors: firmly reseat each RAM module, the GPU (if present), and all power cables (24-pin, 4/8-pin CPU, GPU 6/8-pin). Check any GPU power lead—a loose GPU power plug can mimic a dead video card.
  5. CMOS reset: remove the CMOS battery for a minute (or use the clear-jumper) to reset BIOS defaults; this can clear bad settings that block POST.
  6. PSU and visual checks: inspect the motherboard for bulging/leaking capacitors and burn marks. If available, verify PSU voltages or swap a known-good PSU before condemning the motherboard.

A methodical approach usually reveals a single replaceable part (bad RAM, GPU, PSU, or CMOS issue) rather than requiring a whole new tower. If the recorded beep pattern is available, compare it to the BIOS/vendor beep table for a targeted replacement. Safety note: always unplug mains and ground before touching internal components.

It could be an easy fix. Though some additional information would be needed. What pattern are the beeps (ie two long beeps, two short beeps)?

As chris.stout indicated, these beeps mean something is wrong..obviously. The advantage to the beep codes is that you do not have to have a monitor to determine what the problem is. Depending on hte patern of the beeps, you should be able to determine the issue.

Hi,
I have this exact same desktop, and had this exact same problem
the way I fixed it, is to replace the graphics card.
The beep normally means that the desktop cannot detect a graphics output so it just powers down and makes one long beep
