HP Desk Top 500-214 Now won't boot up. 5 short beeps continuing 5 times

[Beamer2]

My desk top has been working fairly well but it is not used for 7 mos.  When I turned it on 10 days ago it seemed to operate fine and did its Windows Updates. Not when I try to turn it on, I get a LED white light followed by 5 short beep. It cycles 5 or 6 times then the beeping stop and light stays on but doesn't start up. I tried several suggestions from HP Virtual Asst. but still won't start. When I went into the diagnostics it said 5 short beeps is a minor issue rather and 2 long and 3 short. Any suggestions?

Thank you for posting on the HP Support Community.

I appreciate your efforts to try and resolve the issue. This sounds like hardware related issue,
Firstly, let's run Hard Reset:

1. Turn off the computer.

2. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.

3. Unplug the Power adapter from the computer.

4. For most laptops and desktop computers, press and hold the Power button for 15 seconds to reset. (if the computer doesn't start up/power on you can contact our Support and our Support Engineers should be able to sort this out.

Hi and thanks for the reply but I did try that and it did not work. After trying HP told me to use the support[forum for a solution. Who else can I contact to resolve this issue?
