Well, crud. I have a brand new Mini that I was ALMOST done getting set up for work, when all of a sudden it develops a hardware problem. The thing keeps just rebooting, as if the power had flickered off for a second. Got the OS updated, no problem. Installed 2GB of RAM myself, no problem (but MAN is it tight in there--almost as bad as putting RAM in the first-gen iMacs). BootCamp and Windows installation, no problem. Try to update Windows... and the issues start. It's way more prone to doing this under Windows (at first when I tried to do anything with the network now it won't even finish booting), but after half hour of running the MacOS it also does this. Hardware Test CD of course says it's fine. And I tried resetting the SMC and PRAM. So... since I have to tear the thing apart again to put the factory RAM back before sending it in for service, is there anyting in particular I should look at while I'm in there? Maybe something I could have knocked loose or something? (Though I was pretty darn careful.) It'd be nice if it was something obvious and I didn't have to wait another week for service (and hope that AppleCare doesn't notice I goofed with the RAM--no, I'm not certified to do it, but only because I haven't been able to justify the money for the course/test yet).
