Whaaa! Media Keys and resolution issues!


OK, major, major issue here:

After clean install (new format), OS X works fine apart from:

1. Media keys simply don't work: no way to control volume, eject disk etc.

2. On start-up the screen is split into four distorted areas, with a miniture screen in the upper left of the monitor. Once logged in, I can reset the resolution and the screen is fine - but it happens every time.

Any ideas? FYI - 533 G4 (updated firmware) 512MB RAM, nVidia card.

Many thanks in advance!
