Hi @DR-KANTA,

 

Welcome to the HP Support Community!

 

I understand you want to upgrade your HP DreamScreen 400 All-in-One with more RAM, a better processor, and a dedicated GPU.

 

Because the DreamScreen 400 is an All-in-One, its upgrade options are more limited than those of a standard desktop tower. 

The processor and graphics are generally tied to the system board, so a normal CPU or GPU upgrade is not possible in the same way as a desktop PC.

 

A complete system-board replacement would be required for a different processor/graphics configuration, and compatibility would depend on the exact board available for your configuration.

 

RAM may be upgradeable, but I would not recommend purchasing memory until we confirm the exact configuration.

 

Please provide the full product number/SKU of your DreamScreen 400. You can find it on the label on the back of the PC or by pressing Fn + Esc in Windows.

 

Once you provide that, I can check the supported maximum RAM, processor options, graphics configuration, and whether an HP system-board upgrade is available for your specific model.

 

Best regards,
Kuroi_Kenshi
