Hello All, I've got a 1.25 Mac Mini with 256mb Ram (all original, not upgraded). It's running 10.4 Tiger. No problems at all, until today, came to use it and all i'm getting is a small folder with the finder icon and a question mark, alternating. This is before even the grey Apple screen. i've booted from my install DVD and reformatted and reinstalled the OS, twice, still the same, i've been into Disk Utility and the Disk is showing as fine, there's also no errors when installing. I've reset the PRAM, also the NVRAM too, through open firmware. still not getting anywhere. Everything is passing on the hardware test too, so, although i'm not an advanced user, i'm not a novice, and i'm stumped, as is a friend i know who's a lot more knowledgable than me! Thanks in advance!
