My Mac has been crashing several times daily. Programs will randomly crash a minimum of 10 times a day. Sometimes everything just freezes without any indication as to what's happening, but more often than not, I get the following message: "You need to restart your computer. Hold down the Power button for several seconds or press the Restart Button" You can see what the screen looks like at the following site: http://www.mexicanwater.com/my_mac_sucks.jpg I've restarted several times. I've reinstalled Panther several times. Nothing works. I've been a big Mac preacher for a long while, but this makes me want to think twice before saying, "OS X is more stable than Windows" I'm running Panther (a legitimate copy I purchased) on an iBook G3 500MHZ. I have not experienced any crashes on my G3 400 Indigo iMac. Anybody else have a similar problem or know what the F@#* is going on?
