Physically installing most video
cards is very straightforward. Simply choose an available expansion
slot, seat the video card, and connect the monitor. Some combinations
of AGP card and AGP slot are problematic, requiring extra care to
make sure the card actually seats. You may think the card is fully
seated, you may even have felt it snap into place, and yet when you
fire up the system you have either no video or garbled video. If that
occurs, turn off the system and make sure the video card really is
seated.

Many video adapters now come with
heatsinks on the graphics chipset. Some whose chipsets run at very
high speeds go further, adding a fan to the heatsink. If your adapter
has a fan, make sure to connect power to that fan before you use the
adapter. We received mail from a reader who didn't
realize that connecting the fan was mandatory, and so overheated and
damaged his expensive new video adapter.
