Apple Hardware Test
You can use the Apple Hardware Test (AHT) application to help determine if there’s a problem with one of the computer’s components, such as the memory or processor.
To use Apple Hardware Test: Disconnect all external devices from your computer, except the keyboard and mouse. If you have an Ethernet cable connected, disconnect it. Restart your computer while holding down the D key. When the AHT chooser screen appears, select the language for your location. Press the Return key or click the right arrow button. When the AHT main screen appears (after about 45 seconds), follow the onscreen instructions. If AHT detects a problem, it displays an error code. Make a note of the error code before pursuing support options. If AHT doesn’t detect a hardware failure, the problem might be software related.
Important: If Apple Hardware Test doesn’t appear after restarting, hold down the Command (x), Option, and D keys and restart the computer to access Apple Hardware Test from the Internet. Be sure to reconnect your Ethernet cable. Your computer must be connected to a network that has access to the Internet.
