- - - - 3.Test the Theory to Determine Cause
        
        4.Establish a Plan of Action to Resolve the Problem and Implement the Solution
        
        5.Verify Full System Functionality and, if Applicable, Implement Preventive Measures
        
        6.Document Findings, Actions, and Outcomes
  - - - Question the user
        
        Identify any changes made to the computer
        
        Review log files
        
        Inquire as to any environmental or infrastructural change
        
        Review documentation
    - - Create a list of the most common reasons why the error would occur
        
        Start with the easiest or most obvious causes at the top
    - - Determine the exact cause by testing the theories of probable cause one at a time, starting with the quickest and easiest
        
        If the exact cause of the problem has not been determined after all theories have been tested, establish a new theory of probable causes and test it
    - - After the exact cause of the problem is determined, establish a plan of action to resolve the problem and implement the solution
        
        Sometimes quick procedures can determine the exact cause of the problem or even correct the problem
    - - Verify full system functionality and implement any preventive measures if needed.
        
        Ensure that you have not created another problem while repairing the computer.
    - - Discuss the solution with the customer
        
        Have the customer confirm that the problem has been solved
        
        Document the process
        
        Problem description
        
        Steps to resolve the problem
        
        Components used in the repair
  - - - If you see an issue like this, check whether the hard drives are securely connected to the controller and that the controller (if an adapter card) is securely connected to the motherboard
  - - - If nothing is showing up on the display, first make sure that the monitor is plugged into the video card properly
      - Check which video port the monitor is configured to use by accessing the on-screen display (OSD) with the appropriate button on the monitor
      - If necessary, try removing the video card and reseating it carefully
    - - Power cycling the equipment can fix all kinds of problems and is an easy solution to implement.
        
        You might also need to leave a display off for a couple of hours to fix a video memory problem
      - Problems such as video memory (image retention) and stuck pixels might be easily repaired by a power cycle
    - - If you install a new video card to a computer that previously used onboard video, always check that the onboard video setting is disabled in the UEFI or BIOS.
    - - If the resolution was set too high or was set to a resolution not supported by the monitor, you might get a distorted image or no image at all.
    - - Maybe the driver failed, or perhaps the wrong driver was installed during installation, or maybe an update is necessary.
    - - DirectX is a Windows technology that includes video, animation, and sound components.
    - - High-end video cards are intensely used by gamers and designers, and they can be the hottest component in a computer.
        
        If the temperature surpasses the safeguards in place, it might cause the card to throttle back the GPU speed
    - - Check whether the card is seated properly. In areas in which the temperature and humidity change quickly, the card could be unseated due to thermal expansion and contraction
      - If the computer was moved recently, it could cause the card to come out of the slot slightly.
        
        Verify that the power connections and other cables are not loose.
- - - - Updating the BIOS can fix many of these issue
  - - - Swap out the motherboard with a known good one to see if the issue happens again when running through the same processes
  - - - To fix a problem such as a SATA controller failure, a separate PCIe SATA controller card can be purchased.
      - Then can connect the hard drives to the new controller and disable the original integrated SATA controller in the BIOS.
  - - - The affected capacitor(s) should be replaced right away.
- - - - Computer will not boot/intermittently shuts down
      - BIOS indicates a memory error
      - . Stop error, aka BSOD or Blue Screen of Death
    - - Fan failure
      - Fuse failure
      - Quick death
      - Slow death.
      - Always make sure that the power supply cable connects from the power supply itself to a properly wired AC outlet properly before troubleshooting further.
      - Troubleshooting Hard Drives
        
        BIOS does not “see” the drive
        
        First, make sure the power cable is firmly connected and oriented properly
        
        Next, make sure SATA data cables are fully seated in the ports, and weren’t accidentally installed upside down; if you find one that was, consider replacing it because it might be damaged due to incorrect installation
        
        Windows does not “see” a second drive
        
        Slow reaction time
        
        If the system runs slow, it can be because the drive has become fragmented or has been infected with a virus or spyware
        
        Missing files at startup
        
        If you get a message such as BOOTMGR Is Missing, the file needs to be written back to the hard drive.
        
        In severe cases, this can mean that the drive is physically damaged and needs to be replaced
        
        If this happens, the drive needs to be removed from the computer and slaved off to another drive on another system.
        
        Then the data must be copied from the damaged drive to a known good drive (which might require a third-party program), and a new drive must be installed to the affected computer
        
        Other missing/corrupted files
        
        Missing or corrupted files could be the result of hard drive failure, operating system failure, malware infection, user error, and so on.
        
        If this happens more than once, be sure to back up the rest of the data on the drive, and then use the preventative methods
        
        Noisy drive/lockups
        
        If your SATA magnetic disk drive starts getting noisy, it’s a sure sign of impending drive failure.
