importing cdgs to hoster

[Busy Digits]

I am starting to think there are too many services running on my computer. When I look at my system information- it shows 512k but generally 200k max available for use (I watched it fluctuate from 80k to 180k) running different programs. It went as low as 80k when I was on the Windows Update site and the site was scanning my computer.
Anyway, here's some stats:

Systemax 1700+ AMD
512 Ram
40 gig Hard Drive (main)
120 gig Backup and Media storage Drive
CD Rom drive (Stock)
Optiarc DVD RW-AD-717OA 1.02
NVIDIA GeForce 5200 Video Card
I have a card from Pinnicle Studios for capturing video installed but am not using it
Cable Modem
HP 722c Deskjet Printer
This computer is regularly used for internet use and has Avast Antivirus, Zone Alarm and AD-Aware running. I tried using MSCONFIG to turn off certain programs and when I turned them all off--Hoster didnt recognize any disk drives....so the answer could lie somewhere in what is running and not running to maximize my RAM... but I am thinking of getting a New Dell. This is driving me nuts.. Hopefully Bob can help me with this computer.
