Physical Installation Issues
• Two primary issues
1. Long cards• Some video cards are tall
and may not fit in all cases• Get a new case or new
video card
2. Proximity to nearest PCI card– Video cards run very hot– Leave space for ventilation– Good practice is to leave the slot next to an AGP
card empty to allow better airflow

Troubleshooting Monitors
Opening up a monitor can be deadly
Even when the power is disconnected, certain components inside a monitor retain a substantial voltage for an extended period of time. If you accidentally short
one of the components, it could actually kill you!
