How to Troubleshoot Screen Blackouts and Fan Noise When Taking Online Exams with Respondus Lockdown Browser

Question:

What could cause intermittent screen blackouts and loud CPU fan noise when using Respondus Lockdown Browser?

I have a computer that runs games smoothly and quietly, but whenever I use Respondus Lockdown Browser for online exams, the screens go black and then back on, and the CPU fan becomes very loud. This issue started this semester, and I don’t recall making any significant changes to my computer settings or hardware. The only thing I did differently was buying two new Acer monitors over winter break. Could this be related to the problem? How can I fix it? Thank you for your assistance.

Answer:

There are several possible causes for the intermittent screen blackouts and loud CPU fan noise when using Respondus Lockdown Browser. Some of them are:

  • Overheating: Respondus Lockdown Browser is a secure browser that prevents students from accessing other applications or websites during online exams. It may use more CPU and GPU resources than other browsers, especially if the exam involves video or audio recording. This could cause the computer to overheat and trigger the CPU fan to spin faster and louder to cool it down. Overheating could also cause the screens to go black and then back on as a safety measure to prevent damage to the hardware. To prevent overheating, you should ensure that your computer has adequate ventilation, clean the dust from the fan and heatsink, and avoid placing your computer near heat sources or direct sunlight.
  • Incompatible monitors: You mentioned that you bought two new Acer monitors over winter break. It is possible that these monitors are not compatible with your computer or the Respondus Lockdown Browser. For example, they may have different resolutions, refresh rates, or connection types than your previous monitors. This could cause the screens to flicker or go black and then back on when using the Respondus Lockdown Browser. To check if this is the case, you should try using your old monitors or a different monitor with your computer and see if the problem persists. You should also update your graphics card drivers and check the monitor settings to ensure that they match your computer’s specifications.
  • Malware or virus infection: Another possible cause for the intermittent screen blackouts and loud CPU fan noise when using Respondus Lockdown Browser is malware or virus infection. Some malicious programs may interfere with the Respondus Lockdown Browser’s functionality or attempt to access your computer’s resources without your permission. This could cause the CPU fan to spin faster and louder and the screens to go black and then back on as a sign of system instability or corruption. To prevent malware or virus infection, you should scan your computer regularly with a reputable antivirus software and avoid downloading or opening suspicious files or links.
  • These

are some of the most common causes for the intermittent screen blackouts and loud CPU fan noise when using Respondus Lockdown Browser. However, there may be other factors that contribute to the problem, such as faulty hardware, outdated software, or incorrect settings. Therefore, you should always consult a professional technician or the Respondus Lockdown Browser support team if the problem persists or worsens. They may be able to diagnose the exact cause and provide the best solution for your situation. Thank you for your question and I hope this article was helpful.
