A computer is a tool that can help you do your work so that it can be done faster. starting from office work, school work, and other jobs that need the help of this electronic device. However, you know what? Electronic devices are still inseparable from these problems and problems that can hinder your work. The following are some of the most common computer problems.
Dead Pixel or Dot Pixel or Defective Pixel or simply known as “dot” is a term used for problems that occur on the LCD screen, which refers to a defect in the form of dots on the screen. This type of damage is due to a problem with the transistor because each subpixel is represented by a transistor that fires a basic color image, and when one of the transistors has a problem, the image will be biased, causing a dead pixel.
Just like dead pixels, stuck pixels are problems that occur on LCD computer screens. What is a stuck pixel? Stuck pixels are a situation where there is a problem with color dots on your computer screen, be they red, yellow, blue dots, or mixed colors like green orange. This problem causes the screen pixel to become stuck or inoperable.
Like dead pixels, there are also several causes of stuck pixels, including collisions, sudden changes in temperature around the LCD matrix, magnetic fields, hardware faults or it could be due to decreased LCD quality due to age and use.
One of the most common problems with computers is a computer that suddenly cannot be moved or used anymore or more often referred to as a hang. Hang indicates the position or state of the computer that freezes suddenly, where the mouse or keyboard does not respond to commands and cannot be operated so that the computer cannot be used. Hang can happen at any time, even when you are doing the simplest things using a computer. There are several causes of hangs, including; CPU overheating, hard disk problems, viruses, and many others.
Hard Disk Bad Sectors
Bad sectors on a hard disk mean that there are parts, segments, or sectors on the hard disk that are damaged or have problems so that they cannot respond to read or write commands. There are two types of bad sector problems, namely irreparable physical damage and irreparable damage to software.
The cause of the bad sector itself is usually an unstable voltage, the use of a computer that is too long or frequent interruptions of electricity when the computer is being used suddenly.
