To check the motherboard, CPU, and RAM
This procedure verifies that the PC system board and the associated CPU and RAM are
functioning. It assumes that the power supply, display board (when present), and an
external monitor are functioning correctly.
1
Connect an external keyboard to the keyboard port.
2 Connect an external XGA monitor to the video output connector on the rear
panel.
3 Hold down the Tab key on the external keyboard, then press the power button
on the oscilloscope.
4 Verify that a message showing the Main Processor type, memory, CPU Brand,
IDE Drives, etc. momentarily appears on the monitor. The message will only
appear momentarily, then it will disappear.
5 If the message is displayed, you can assume that the PC system board, CPU,
and RAM are functioning correctly.
If you need to run setup, press DEL. Otherwise, turn off the power and proceed with
troubleshooting.
