What's the second thing you do when you think your PC has a hardware problem (after you check the cables)? You reinstall the device drivers for the suspect component. But that means hunting down model numbers, looking for CDs, and maybe downloading files. WinDriver Ghost backs up all your device drivers and reinstalls one driver or many with just a few mouse clicks. The program is especially handy for keeping hand-me-down PCs with unknown hardware running smoothly. It's free to try, and only $25 to keep.
