Troubleshoot System and Display Issues Flashcards
5.2 Given a scenario, troubleshoot problems related to motherboards, RAM, CPU, and power. 5.4 Given a scenario, troubleshoot video, projector, and display issues.
What cause might you suspect if a PC experiences intermittent lockups?
Assuming the cause is not related to software or device drivers, then thermal or power problems are most likely. Loose connections, faulty system components (motherboard, CPU, and memory), and corruption of OS files due to bad sectors/blocks are also possibilities.
True or false? Running the fans continually at maximum speed is the best way to prevent overheating.
False. This is likely to damage the fans and draw more dust into the case. It will also cause a lot of excess noise. To prevent overheating, the PC should be installed to a suitable location (away from direct sunlight and radiators) and cleaned and maintained to a schedule.
You receive a support call from a lecturer. A projector is only displaying a very dim image. Which component should you prioritize for investigation?
A dim image is likely to be caused by a blow bulb (or one that is about to blow). If there is no visible sign of damage to the bulb, you should rule out a simple configuration issue, such as the brightness control being turned all the way down.
A user has been supplied with a monitor from stores as a temporary replacement. However, the user reports that the device is unusable because of a thick green band across the middle of the screen. What technique could you use to diagnose the cause?
Replace the cable with a known good one. If this does not solve the problem, suspect an issue with the monitor. As the PC was used with no issues with another monitor, there is not likely to be an issue with the video card.
