the keyboard and mouse.
3. Remove all add-on cards.
4. Install a CPU (making sure it is fully seated), the chassis speaker and the
power LED to the motherboard. (Check all jumper settings as well.)
5. Install a single memory module and make sure it is fully seated.
6. Check the power supply voltage 115V/230V switch.
No Power
