So I was so overjoyed that my new iMac with Radeon 4850 was freeze-free after installing the firmware update that I installed Vista and some games. But everytime I try to boot into Windows I get a BSOD with the message "Internal_Power_Error" and it just restarts. I can boot into Safe Mode but I don't know what I could possibly do from there. So I restart and try lots of different options in the boot menu and all of them give me the same BSOD. Strangely, I'd try Use Last Known Good Configuration and it wouldn't work, then 2 tries later it does work. But most of the time it doesn't. Anyone have any ideas on what to do? iMac (2009) 2.93 GHz Core 2 Duo ATI Radeon HD 4850 4GB RAM 640GB HDD with 150GB Boot Camp partition Vista Ultimate 32-bit Thanks!
