So I got a great deal on a G4 powermac 733 mhz dig audio a few years back and it has served me well, but i bought it with one known flaw: after you start up, eventually It locks up and you get the screen that says you need to restart your computer. After I restart, I have never had it freeze, so I simply restart everytime and it works great. I have done a clean install of osx but that didn't solve the problem. Wierd a? I'd love to get it fixed if i could. If you know anyway to help me out that would be great.
