Computer systems are made up of interconnected parts, so a malfunction in one part can affect others. To ensure steady computing, all parts must be kept in good working condition. Most computer problems are related to loose or faulty connections between parts, so cleaning and tightening connections is a first step to troubleshooting. Regularly using cleaning and security software, like antivirus and anti-adware programs, can help prevent issues by removing excess files and protecting against viruses and other threats. Formatting is a last resort solution if problems cannot be resolved through other troubleshooting methods.
