ing any hardware components.

Before Power On

sis.

keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis

speaker and the power LED to the motherboard. (Check all jumper settings

as well.)

No Power

sis..

2. Make sure that all jumpers are set to their default positions.
