New Purchase .. HP 23.8 in all-in-one desktop pc cr-0114 Need help setting up

[ameenah5]

I just purchased a HP 23.8 inch all-in-one desktop pc cr-0114.   I have plugged in the:

   power cord

   keyboard (cord), and

   mouse (cord)

The system gives a series of loud beeps

Flashes what looks like program language quickly and then the screen goes black

I cannot get the screen to appear on the monitor that would guide me through further steps to setup.

Please help

@ameenah5, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Based on your description, the loud beeps and flashing screen followed by a black output suggest a hardware-level error occurring before the system can even boot to Windows or the setup screen. Here’s a step-by-step guide to help you diagnose and resolve the issue:

Count the Beeps

HP uses beep codes to indicate hardware issues (e.g., RAM, CPU, display, etc.).

• Count how many beeps you hear and whether they are long or short.
• For example, 3 short beeps may indicate a memory error, while 5 beeps could signal a system board failure.

Power Cycle the PC

• Disconnect the power cord.
• Hold down the power button for 15 seconds.
• Reconnect the power cord and try turning it on again.

Perform a CMOS Reset (if possible)

Sometimes resetting the BIOS helps:

• Look for a small CMOS battery (coin-cell battery) at the back if accessible.
• Remove it for 1–2 minutes and then reinsert it. (Note: Some All-in-Ones require opening the back panel, which may void the warranty. Skip this if unsure.)

Check the Display

• Shine a flashlight at an angle on the screen when it’s black. If you can faintly see the setup screen, the backlight or display cable might be faulty.
• Try connecting an external monitor via HDMI (if the All-in-One has an HDMI out) to test if the system boots properly.

Reseat the RAM (if accessible)

• If you’re comfortable opening the back panel:
  • Carefully remove and reinsert the RAM stick(s).
  • Power on the PC again.

If the issue persists, we suggest you please visit the nearest HP authorized service center, the service team will check and assist you.
