Beeping Code at startup

Pavillion AIO touchscreen
Microsoft Windows 10 (64-bit)

Ok so I have read multiple solutions to this issue on various sites including this forum and none of them have worked for me. Every time I start my PC it emitts 3 long beeps and 4 short beeps 5 times and then starts normally. I keep reading that is an issue with the keyboard and mouse and I have done everything I've found to try to resolve it. Ive unplugged them, restarted, plugged them back in, changed the batteries in my keyboard, changed the ports they're plugged into, Ive tried trouble-shooting through the HP Assistant and Ive even done a Hard Reset, nothing has fixed the issue. Other than the beeping my PC is completely normal, everything is up to date and such, is there anything else I can do to fix this?

Beeping Code at startup



The following link does not explain much


It can be 


  • Fatal errors related to the operation of critical motherboard components - such as the CPU. or
  • Flash EPROM not detected

Both are hardware related. Please bring it to a repairer and hopw they can work this out for you/
