Discussion Topic:

There is a diagnosis of a bad video card on a client’s computer made by  another technician. The client would like to have a new video card  installed on the desktop. How would you ensure that the diagnosis is correct? If it is correct, explain the steps you would take to ensure a new video card is properly installed.

Paragraph #1
Video cards have their own  processors called graphic processing units (GPUs) or visual processing  unit (VPUs). (Andrew, West & Dark, 2017) Before installing a new  video card, I would double-check to make sure my diagnosis matches the  other technician diagnosis. First, I would check to make sure that the  video card, in fact, needs to be replaced. Some signs of a bad video  card are screen glitches, stuttering, and fan speed. I would also check  to make sure there is no dust creating problems with the video card and  checking to make sure the cables are good by testing the other cables  and monitors to prove whether or not the video card is bad. “One of the  easiest, and yet most powerful, techniques is to simply swap out the  graphics card for another one and see if the problems go away”. (Hayes,  2019, p. 3) Below are the steps I would take to install a new card:

  1. Turn off the computer and unplug from the wall. 
  2. Open the case to gain access to where the video card is located on the motherboard.  
  3. Unscrew  the screws from the retention bracket to remove the faulty video,  making sure all the wires that are connected to it are unplugged. 
  4. Install the new video card into the open slot making sure all wires are plugged in correctly and close the case side panel. 
  5. Turn  the computer on, checking make sure the video card is working  correctly, and the latest driver package is installed on the PC.  

“The moment of truth for  any PC hardware change – see if it works. Double-check you’ve done  everything correctly so far. Then, before putting your whole PC back  together and plugging everything in, plug in the power cable, your  keyboard and mouse, and a single monitor video cable. Then turn your PC  on and see if you get a picture”.  (Martindale, 2019, p. 13).

Paragraph 2
  Bad video card           

In order to determine if the diagnosis of a bad graphics card is  correct or not, I would start by first making sure that the graphics  card is properly seated on the motherboard. I would then check all of  the cables and make sure that none of them are loose. I would then check  the graphics settings on the computer to make sure that it is set  correctly. I would uninstall the current drivers for the graphics card  and reinstall the last stable drivers that are available. I would run a  program like MSI afterburner, which monitors the graphics card  temperatures to make sure that it is not overheating. Overheated  graphics cards can cause damage to itself or other components. It is  important to also check the monitors being used as visual issues could  be a symptom that your monitor is about to fail. You can test this by  using a different monitor. I would also recommend checking the device  manager in Windows control panel to see if the graphics card is listed  as working correctly. If there are no problems found with the device, it  will say “this device is working properly” or something similar. I  would also check the fan speeds of the graphics card. If the fans are  constantly running at high speeds or never running at all there could be  a problem with the graphics card. You should clean the fans by spraying  compressed air to make sure they are not covered with dust (Batt,  2017).
