When my PC switches on it immediately makes a continuous series of short beeps. Nothing else! Ideas?

HP ENVY All-in-One - 27-b105na
Microsoft Windows 10 (64-bit)

I’ve been through all the diagnostics, and none of the descriptions of the error codes/beeps matches my problem. I’d welcome any wisdom.

thanks

Which diagnostics have you run?

 

From the suport portal, you should be able to access the PC Hardware Diagnostic UEFI utility from boot by tapping the F2 key immediately after powering on.

 

List the diagnostics you have run in detail.

 

Run the long system test and kindly provide the result .

 

One beep is a CPU failure, two beeps is BIOS corruption and three beeps is a memory module issue.

Thanks,  but that doesn’t help. I tried pressing F2 from boot and that doesn’t work. I also managed to get hold of Customer Support today and they recommended windows+B but that did not work either.

 

When I say a ran diagnostics I mean that I followed the recommendations of the virtual assistant which wasn’t very helpful.  I reviewed the beep codes that they described and none of these matched the single tone, short, repetitive and high pitch beep that this machine gives off.

 

kind regards

Can you make a video with sound from your mobile phone, post it to a hosting site, say for example, Dropbox and then post a link to it here in your thread?

 

You may be miscounting the beeps. Watch for blinking LEDs.

The motherboard might be trying to signal that the processor is overheating.

 

Power-off the computer.

Disconnect the AC power.

Remove the side-panel, to expose the motherboard.

Locate the fan on top of the processor.

Try to "spin" its blades by hand -- if it does not spin freely, it has "seized", and must be replaced.

Reconnect the AC power.

Power-on the computer, and visually check that the fan spins.
