Continuous beeping noises after turning computer on

[Maria125]

Product name : HP Pavilion All-in-One 24-xa0xxx

Product number : 4NM47AA#ABA

Hello! My computer that I am using right now was beeping continuously more than 7-8 times before I unplugged it. I tried counting the beeps, and I believe there were 3-4 beeps after that were beeps that sounded somewhat louder. I began to do research on my phone to help stop the beeping when I turn it on, and I found one info that said to unplug the computer charger and hold down the power button for about 15 seconds. After I did that, I put my charger back in, and my computer turned on as normal and was working with no more beeping. Will this happen again? Should I worry about this? Do I have to fix something immediately?

I just want to know if the beeps were telling me something, that my desktop is malfunctioning in a way or not. Please provide me as much info as you can, thank you in advanced!

Software failures will generate on-screen messages, usually about not finding an Operating System or not being able to boot. When the screen is blank, the PC is experiencing a major hardware failure.
--------------------
If the CapsLock key is blinking or there is beeping, read this HP information on the likely cause of the hardware failure based on the blinking or beeping patters.

For desktops, this HP thread describes the different blink and beep codes: https://support.hp.com/us-en/document/bph07107?jumpid=reg_r1002_usen_c-001_title_r0001
--------------------
To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
