Hello all, I have a G4 Mirror Door Dual 1.25 Ghz with 2GB ram, and an 80gig IDE hard drive (Western Digital). I bought it used off of ebay recently. It only came with a fresh install of 10.4 so I got the updates from apple to 10.4.11. After installing some applications I noticed that at least once during each session I use the G4 it will lock up or freeze, which almost always leads me to have to just unplug the G4 to shut it down and then I plug it back in and restart it. My question is this, Is Tiger 10.4.11 buggy/glitchey and is lockup prone, or could this be a hardware issue such as a bad ram module causing this? Help me MacRumors:Forums, your my only hope.
