I tried the PRAM trick several times, but no success. I cheked the "About this Mac" and discovered that (under PCI/AGP) there is no videocard at all shown. This means that there must have happened (after I pressed this reset/cudaswitch on the inside) that made the videocard invisible. So how to get the Cube to recognize the fact that there is a card installed? Met vriendelijke groeten, Ton van Hest -------------- next part -------------- A non-text attachment was scrubbed...
