    My mac mini G4 (1.42 GHz), which was working fine before, now display video only during the gray screen at startup... after that, the screen goes black. The problem started when i changed the desktop background pic for a new one... The video output became distorted and the screen turned black shortly after.

    I tried resetting the PRAM and PMU, as i've read here, but that doesn't change anything.

    Thanks for any help!
