My G5 is about a month old and it freezes sporatically throughout the day, always in Safari. I took it to the Apple Store after consulting phone support and they said they couldn't replicate the problem. It just ramdomly locks up, I tried a clean install twice but nothing. Since the guy couldn't make it freeze, I think it has something to do with the video card. He had a regular monitor and I have a Samsung Syncmaster Widescreen running at 1280x768 at 60Hz. Oh, its a single 1.6 witha gforce card and 256 ram. Its not the ram either because I switched em out and it didn't help. Please, someone I'm despirate!!!
