So, I've got a White iMac late 2006 model that's stuck at the white screen. I can still boot into safe mode, but other then that, I really don't know what to do. I can also boot into Verbose and Single User Mode, so is there something I can look for when in Verbose mode, so that I can figure out what the issue is? The iMac has a 1TB HDD, 2GB RAM, and the latest OSX Lion installed. Any help would be greatly appreciated. The graphics card was recently upgraded; the previous user I guess decided to put the 7600GT instead of the stock 7300GT in it, and forgot to put thermal paste on it, but I fixed that. Just stuck on the White Screen. I've tried Command+Option+P+R and Command+Option+P+L and still no luck. Thanks!
