Add memory to the machine and it should resolve your issues. The 2840 comes with 96MB built-in and has one slot open for additional memory located under the right side cover. It can take a max of 224MB total. I would recommend adding a 128MB memory card to max out the machine. It takes 100 pin, 133MHz, SDRAM.
Don't by it from HP as they list it at $500.00 or so. Buy the clone memory for around $25.00 for 128MB.
Here's a link to source the memory:
Hope that helps you.
