About two years ago I went to start up my Cube, and it just wouldn't "stay" turned on for more than a split second. This is extremely difficult to describe in text, but it went "DONGGGGG... blaaaaaaah" to shut down mode again. No dice on getting a solid start using a CD and so on and so on. It feels like a hardware problem. Anybody else experienced this? Since I have five other Macs here too (2 G4s, a Wallstreet PB, and an iMac), I've never bother to get too worked up over my Cube doorstop. I can't justify the expense of bringing it to be fixed, but I hate to just see it sitting there looking great but completely cold and silent (just like my ex-wife). Suggestions? Thanks in advance!
