Six beeps is indicating an issue with the graphics card.

1.  Ensure the graphics card is plugged into slot 2 (2nd closest slot to the CPU).

2.  Try removing and re-seating the graphics card.

3.  Confirm that the auxilliary power connector(s) is/are plugged into the graphics card if required.

NOTE: If the graphics card is 75W or less, there won't be any auxilliary power connectors on the card.


Does the front LED (power button) flash, and if yes, what colour does it flash, red or blue?

What graphics card do you have installed?
