Ok I need to get some info here on upgrading memory and graphics cards for this computer. I tried to do a disk frag and it says I only have 1% free space.

My computer is a Dell OptiPlex GX260 with 2.4 mHz speed. Here are the specs I believe I have:

Total physical memory: 512mb
Available physical memory: 145mb
Total virtual: 2gb
Available virtual: 1.96gb

Is there any other info I need to provide for help on this?

Graphics:

I have an Intel 82845G/GL/GE/PE/GV Graphics controller. What can I do to upgrade this, but inexpensively?

Thanks. Later, QD.
