BAD PC problem HELP

The difficulties you're having are so severe that it almost seems like a hardware/software incompatibility issue. Was Windows/XP the original operating system installed on your PC? If not you might want to check if your PC is compatible with XP.--Percy

I actually asked whether your computer had Windows/XP on it when it was new, but this information may answer the question anyway. A FAT file system is not used by Windows/XP. It was used up through all Windows predecessors to Windows/XP, but not before. If you once had a FAT file system on your computer, then it was not a Windows/XP operating system.This means that your computer may not be compatible with Windows/XP. You can often check with the manufacturer concerning Windows/XP compatibility. If you know what version of Windows was originally on your computer then returning to that version may fix many of your problems.--Percy

Linux is not just another download that runs under Windows. It's a replacement for Windows, not just another thingymajigwotsit. Do not attempt to download and install Linux casually. If you do you won't be in Kansas anymore, or for those in the post-WOZ generation, all the familiarity of Windows will be gone, it will be like trying to get around in a foreign city where no one speaks English.I use Linux in my daily work. The number of Windows applications that do not run on Linux is legion. The number of people and discussion boards you can go to for help, compared to Windows, is sparse, and a significant proportion of them are using Linux for work rather than fun. While many things you can do in Windows can also be done in Linux, where and how you do them is not the same, so there's a significant learning curve.I wouldn't recommend Linux as a solution for amateurs. As you attempt to get Linux up and running there will be many times when you're wondering, "What the heck do I do next," and if you can't get online then it's very unlikely that any of your friends or neighbors will be able to help you.--Percy
