Hello! My iMac G5(rev A it did have that common fault that lots of iMac G5 Rec As did(with the smoke smell and yello puse on the inside) but was fixed by Apple So i was using handbreak to rip some DVDs to my Mac. I also had QemuX to try and get XP and Linux on it.(never worked). I left to go to a party and left handbreak on ,ripping a DVD(it worked) and i think i left QemuX running but im not sure. So i came home and wake my iMac up. BAM it shuts down. I'm think "werid but a reboot should fix it" so i reboot. It gets to the grey Apple screen and BAM crashes agian. I keep trying each time i get to different places sometime to the web sometime does not even get to the blue backround with " Mac OSX starting up" So now i have no idea what to do? So went to MR for help. So think it hardware or software or BOTH? should i go to Apple Store and have them check it out? Anyy ideas?
