Note: The magnitude of interference, noise or distortion depends on your screen's proximity to sources such as TV sets, mobile phones, other monitors, refrigerators, large stereo speakers, power adapters, halogen lighting with built-in power supply or motor driven appliances. Faulty fluorescent light assemblies or the proximity to high voltage lines can also cause distorted images. Place your computer as far as possible from these sources. If there is no source of interference, or removing the source of interference does not alleviate the symptoms, please refer to your monitor documentation to perform a series of screen adjustments (image size and position, refresh rate, degauss, etc.). Certain adjustments may not be available, depending on the display technology used. Sound Upon Startup, My Computer Emits a Continuous Beeping Sound 1.
