Is blue smoke coming out of your computer? Windows won't load and you only see a black screen? Or does Windows load, but then the screen turns blue and “crackers” run across it? Is there a piercing squeak coming from the system unit? Do not panic! And don’t rush to call a specialist. In most cases, computer crashes can be “healed” on your own. This book will teach you how. It tells you very simply about the most common PC breakdowns. Both hardware failures and failures at the operating system and software levels are considered. Viruses and malware are discussed separately.
