You're lucky I decided to include the Oasis in my rounds. I am an expert for getting passed these problems. Here's what I'll need. I need to see your autoexec.bat and config.sys files as well as what the computer displays when you run mem in windows (mem is in the windows/command folder). Post them here or email them to me. I'll also need to know what type of sound card you have in case the audio problem isn't memory related. With that info I should be able to save you from using a boot disk.
