• Disconnect all internal and external peripherals, and re-start the computer. If the
computer boots, add the peripheral cards back one by one until you find the bad one.
• If the problem persists, the system board is faulty.
• If two or more memory modules are installed, remove the modules, then re-install one
module and re-start the computer. If the computer starts normally, continue to install
additional memory modules (one at a time) until you have identified a faulty module or
reinstalled all modules without error.
• If available, install working memory of the same type into your computer.
