Well, the title pretty much says it all. I recently traded my Powerbook for a Powermac G4 800Mhz DP, after the Powerbook's Superdrive broke.
Anyway, I was told by the previous owner that it sometimes randomly turns off during things like some more complicated 3D games, and resizing large images in Photoshop. I've been using it for a few hours by this point(I've even Geekbenched it) and it hasn't actually turned off yet. I was just wondering if anybody had a clue what the problem is so I can remedy it before it turns off when I'm working on something important. My guess is that it's either overheating or the PSU is going. Any ideas? (I know, I've been using Macs for like 6 months now, so I should know this.)
