Over time, any Windows computer becomes slower than when purchased. Installed and removed programs, temporary files, registry errors and background processes overload RAM and the processor. A clean operating system installation is often the best solution.
The first obvious reason is severe malware attacks. Endless advertising pop-ups, ransomware-encrypted files or missing system files may not be fully resolved by a simple antivirus scan. A clean format guarantees 100% cleanliness.
The second sign is critical system failure, the Blue Screen of Death (BSOD). If it is not caused by physical component damage such as burned-out RAM or SSD, corrupted drivers and system conflicts are removed by a fresh operating system installation.
The most important rule is data safety. Never begin without transferring important documents, photographs, the 1C database and browser passwords to secure external storage. A professional approach guarantees that no important file is lost.
