Hi Dan,

Thank you for waiting!

A non Detected HDD or a defecive HDD will not cause a computer to Beep.

Check your memory, Remove it blow some air in the port where you removed it and place it back in Firmly.

Let me know how this goes.

Open the desktop cover

The memory should be somewhere here "I circled it in RED"

It should look like this

To remove it push the white TABS on the side of it away from the memory and that should release the memory

To put it back in just pushed in downward till it sanps in to place.

OK I'll stand by for your reply then,

Try using other Memory slot remove the memory and try another memory port.

All things inside the Computer tower are sensitive.

Most of the removable parts inside this are not screwed fixed but ports and cartridges.

We cannot point your problem to the HDD as it does not contribute to the error you're getting.

Definitely it is a hardware but I will not say it is the HDD that you replaced.

How many memory card do you have?

Try one first.

One card only on Port 1 then turn your computer ON

You said you have 4 memory card port right?

We'll just call them ports 1 to 4

Start either from the left most port and call that Memory port 1 

try one card only and check

another port with same card

Yes till you have use all ports.

then go with another card starting from port 1

Yes try that to all and let me know what are the difference. 

Take notes as you move along

Ok let me know the result of the others.

can you try no in two's

two card an same time

Do you know if this computer have a video card?

I mean removable graphics card ?

How about a built in to the motherboard?

If the mother board has a video output in it to plug in a monitor?

If you remove the video card,

Will there be a Video port left in the motherboard for your Monitor.

Do you have a way to send pictures on the internals?

i can give you my email to send it to.

Ok send to me

f**0@gmail.com

I'll check it

more picture and angle  the better

Ok hold on

Ok that Radeon Video card,

Remove it Blow some air in ints slot.

Plug it back in Firmly make sure wires to it are Firmly connected

Use just one Memory card in one slot

No changes in the Beeps and how it behave?

Can you try installing all memory card in?

Besure to check the Radeon Video card wirings ok

Can you try turning it ON with out Memory card

same beep pattern?

So be clear there is a difference on the beep patter when a memory is IN and out

It means your Memory card is working if there is a difference.

Can you now try it without that Radeon video card but with the memory IN

One card

Yes

With Video card and without Video card same pattern?

Currently you do not have the video card in right?

Can you remove the memory now and let me know if the patter changes

Ok put the all memory IN

You memory card are fine.

Problem is with your video card.

Try removing the Videocard again.

Clean the copper connectors of the Video card with a pencil eraser.

And try to connect it FIRM as possible.

Yes your Memory cards are OK

Try removing the Videocard .

Clean the copper connectors of the Video card with a pencil eraser.

Then Connect it back as firm as possible

With our lack of spare to test out parts.

I would say it is either your videocard or Motherboard.

If you can bring your tower to local tech which can test their video card testers you will be able to pinpoint the problem.

Bestbuy i would say or any local Computer repair will be fine

Dear Dan, It was a pleasure helping you with your HP issue today. Here is a summary of the resolution.
Issue identified : No POST Problem
Solution Implemented : Verified Memory is working fine since Behaviour changed when installed and not installed

Advised to have the Video graphics check to local store since no replacement test part

If failed will leave a bad Motherboard
