Thanks for all the advice. I only bought the computer last year so I'm not ready to buy a new one. I'm in Australia so your prices, John, are the stuff of dreams! Already have a CD writer. I think I'll start with the RAM upgrade and later see if I need more hard drive. Upgrading the system would be nice but I have no idea which to go for - Windows NT? 2000? I hear good and bad about everything. I just know that I hate Windows ME.
