Theres nothing wrong with your hardware, I had Windows XP Home Edition, I played OFP, and all I got was LAGG LAGG LAGG. I have 1.5Ghz P4, with 20GB HD, DSL, and 256mb of RDRAM. That should be sufficiant to run XP and my games. But since XP is pretty much crash resistant, its busy running 17 programs at a time to keep your computer running safe. After I saw Win XP Home Edition, could not run on my screaming computer, I went back to Windows ME. Tada! No more problems. I was very dissapointed in XP, Made me feel like a newbie to computers again... When I accualy am very computer literate. I hope this helps.
