For more than 25 years, Upgrading and Repairing PCs has been the world’s #1 task to PC hardware: The single source for reliable information on how PCs work, troubleshooting and fixing problems, adding hardware, optimizing performance, and building new PCs.

Upgrading and Repairing PC’s the basics of modern computer upgrade, troubleshooting, maintenance and repair. Emphasis is placed on component identification and diagnosis of software and hardware related problems as outlined in the requirements of the Comp TIA A+ Industry Certification.

With entry-level PCs selling for less than $500 and fully equipped mainstream PCs selling for $1,200, you might wonder if it's even worthwhile to repair or upgrade your old system. After all, a new system comes with a warranty, all new software, and shiny new parts. The problem is and we'll try to put this politely a cheap new system is just that. Cheap. Year after year, consumer-grade, mass-market PCs are cost-reduced more and more. That shiny new cheap system comes with a cheap, unreliable motherboard; a small, slow hard drive; barely adequate memory; a marginal power supply; and so on. There Ain't No Such Thing As A Free Lunch.
Is it impossible, then, to buy a good system, manufactured with high-quality components? Of course not, but don't expect to get it at a bargain price. Business-grade systems from name-brand vendors and systems targeted at gamers and other enthusiasts use high-quality components, but those systems are priced 50% to 200% higher than consumer-grade, mass-market systems. If you compare apples to apples, you'll often find that it's cheaper overall to repair or upgrade your current system than to buy an equivalent new system.
