    Can't quite figure this one out, but I had problems with this when I tried upgrading my RAM with OWC 4GB (single stick). I am using Apple's latest base Mac Mini 2.4 C2D with 2GB RAM.

    Switched back to stock 2GB that came with the unit and haven't had problems since. Just a few days ago, I came home and woke my computer from sleep and had the same fuzzy whitish colorish screen (I know this is bad English, but stick with me here). It looks the same as an old TV trying to tune in a station, but much smaller pixels. After about 5 seconds, everything went back to normal and I haven't had problems since. Any thoughts on what this could be? Bad GPU, bad RAM?, bad logic unit?

    Run hardware test.

    What monitor/s and how are they connected?

    Cheers

    Hadn't thought of running a hardware test. Thanks.

    I am using an 22" Viewsonic LED connected via MiniDisplay Port/MiniDisplay-DVI adapter.
