Well go onine and purchase an XP disc, or use your old one. I dont understand why its slow to you though, just about everything about the OS is quicker than XP. I personally did have some slow startups at first but thats because this PC came preloaded with Norton Bloatware, uninstalled its much better.
Many thanks for telling me to get rid of that preloaded Norton , as you called it "bloatware"... My computer is lighting quick compared to when that was active. Thanks again =s=
