How to Fix Boot Issues After Upgrading HP Pavilion 590-p0127cb RAM

Select Language:

If you’ve recently upgraded your HP Pavilion 590-p0127cb by replacing 1 stick of 4GB DDR4 2666 RAM with two sticks of 16GB DDR4 2666 RAM, and you’re experiencing boot issues, you’re not alone. Even if HP’s diagnostics confirm the memory is functioning correctly, you might still see a spinning circle under the HP logo during startup, get stuck on a black screen with the monitor on, or see a diagnosis message instead of Windows loading properly.

Here’s a simple solution to fix this problem and get your computer to boot normally:

First, double-check that the new RAM modules are installed correctly. Turn off your PC and unplug it from the power source. Carefully remove the memory sticks and then reseat them firmly into their slots. Sometimes, a loose connection can cause boot issues.

Next, reset the BIOS settings to ensure the system recognizes the new memory configurations properly. You can do this by turning on your PC and repeatedly pressing the F10 key (or the key designated for BIOS access on your model) to enter the BIOS setup. Once inside, look for an option to ‘Reset to Default Settings’ or ‘Load Setup Defaults,’ and confirm the change. Save the settings and restart the computer.

If the problem persists, try booting with only one of the new RAM sticks installed. This can help identify if one of the modules or slots may be causing the issue. If your PC boots successfully with one stick, add the second one back and check again.

Make sure your computer’s BIOS is up to date. Visit HP’s official website and search for your model to see if a BIOS update is available. Follow their instructions carefully to update your BIOS, as this can improve memory compatibility.

Lastly, since your system supports up to 32GB of RAM, confirm that both your RAM modules are compatible with your system. Using identical and compatible modules helps prevent issues like black screens or boot stalls.

Following these steps usually resolves startup problems after a RAM upgrade. If issues still occur, consider consulting with a professional technician or HP support for further assistance.
