My Cube (with a Sonnet upgrade 1.2 Ghz up grade processor card) does not engage the monitor any longer. Apple Knowledge base suggests testing it on a known good monitor (which I've done and it still does not work) , checking the power connection to the card (all seem OK). Is there anything else I should look into? It is a ATI Rage with a heat sink, no fan. What is available as replacement that doesn't require alteration of the Cube, searching the Earth, paying a fortune and needs a fan.
