Unformatted text preview: t cleaning solution is designed exactly for this purpose, cleans contacts nicely, and doesn’t leave any residue. You can find contact cleaning solution at any electronics store. A fully inserted expansion card sits flush against the back of the PC case—assuming the motherboard is mounted properly, of course—with no gap between the mounting bracket on the card and the screw hole on the case. If the card is properly seated, no contacts are exposed above the slot. Figure 8-29 shows a properly seated (meaning fitted snugly in the slot) expansion card. Step 3: Device Drivers You know from Chapter 7, “BIOS and CMOS,” that all devices, whether built into the motherboard or added along the way, require BIOS. For almost all expansion cards, that BIOS comes in the form of device drivers—software support programs—loaded from a CD-ROM disc provided by the card manufacturer. Installing device drivers is fairly straightforward. You should use the correct drivers— kind of obvious, but you’d be surprised how many techs mess this up—and, if you’re upgrading, you might have to unload current drivers before loading new drivers. Finally, if you have a problem, you may need to uninstall the drivers you just loaded or, with Windows XP or Vista, roll back to earlier, more stable drivers. Getting the Correct Drivers To be sure you have the best possible driver you can get for your device, you should always check the manufacturer’s Web site. The drivers that come with a device may work well, but odds are good that you’ll find a newer and better driver on the Web site. How do you know that the drivers on the Web site are newer? First, take the easy route: look on the CD. Often the version is printed right on the CD itself. If it’s not printed there, you’re going to have to load the CD in your CD-ROM drive and poke around. Many driver discs have an AutoRun screen that advertises the version. If nothing is on the pop-up screen, look for a Readme file (Figure 8-30). Driver or Device? In almost all cases, you should install the device driver after you install the device. Without the device installed, the driver installation will not see the device and will give an error scre...
