My second PC is an old Dell Dimension 2350 running Windows XP Home SP3 and IE7. So far, I think I would just as soon stay with XP Home instead of upgrading. I noticed that the hard drive is formatted with the old FAT system. Would there be any benefit to reformatting the drive and using the NTFS system? I have the original recovery CD, so that shouldn't be any problem. Anyone have any hints or tips before I start the process?
