This guide will show you how to replace the motherboard of the Dell Vostro 5510. The motherboard is the part of a computer which connects all of its internal components and transmits both information and power. A typical symptom of a faulty motherboard is a totally dead system; however, it is common for a power supply issue to be confused with a motherboard issue. If the system remains dead after replacing the power supply, there is most likely a problem with the motherboard. See this link for more information on motherboard troubleshooting: Computer Motherboard Troubleshooting.
