You have a Dell Dimension 2400 running a Pentium 4 at 2.8 GHz, using Puppy Linux. You're seeing performance issues with spikes to 100% and frequent freezes when launching apps. It seems this setup isn't suitable for modern tasks like retro gaming or general use.
It won't require Prescott CPUs and supports 2GB RAM... unless you're not updating most of the internal components (and then what's the point?), in which case my ideas are limited. You might be better off using a Raspberry Pi to maximize its potential. A practical scenario could be an older gaming setup if it still has a floppy port, for instance running classic DOS titles. Today's systems (including Windows 10) no longer include BIOS code for a 5.25" floppy drive.
