I'm here trying to install Windows via BootCamp on a couple of new Macs for where I work. Updated everything on the Macs, installed the latest firmware, Slipstreamed an SP2 install disc, and got ready to go. First one (17" iMac) worked perfectly. Had some trouble getting Windows to recognize my AirPort network, but eventually just turned off security for a bit and it worked fine. Installed all the Windows patches (50 some of them--does MS have a rollup I can put on CD hidden somewhere for anything but the Media Center edition?), and called it good. Now I'm trying to do the same for a Mini (higher-end version, 2GB of RAM that I installed myself--MAN those are tight inside). BootCamp works fine, the Windows install works fine, the Mac driver install works fine, and then I go to Windows Update. The first-round Installer update works fine, and I start checking for the rest of the updates... and the Mini suddenly reboots. No BSOD, no error message, just "Bong!" and it starts up Windows again, as if the power had flickered off for a second. Disk check runs and fixes something, then I try again... Blink, reboot. So I try uninstalling the updates I installed, and re-running them. Blink, on-again-off-again. I try "Repairing" Windows (basically a reinstall), and this time it blinks out when I'm trying to connect to the wireless network. Now I'm reformatting the Windows partition and starting over completely from scratch, but that's another 2 hour install, and I don't even know if it will help. So... 1) Has anybody else seen this "No BSOD crash"? A BSOD, at least I'd understand, but I've never seen Windows just blink off like that. 2) Any suggestions? Being that it SEEMS to be triggered by network access (though not immediately), I'm suspicious of the wireless drivers, but it was fine in an iMac in an identical situation. I sure as hell hope this isn't a hardware issue because I don't want to have to tear the thing apart again to put the stock RAM back before sending it in for service (plus it's brand new), but I can't imagine that it is--the MacOS works fine, including when doing similar stuff (downloading files, etc.). Argh!
