Replaced hard drive in my Dell 8300 and reinstalled winxp home with sp3. Everything seems to work very good except when I try to install a very simple game it says not enough space on c drive . This is a 250 g hard drive, same size as the one I took out. The only thing on this drive at this time is the OS. I'm using this PC just for my older games that have always worked fine on this PC. Thanks
