[QUOTE="Mamamia, post: 1468315, member: 278207"] My Power Mac G5 (late 2005) with 5 GB RAM, has been having issues with sudden shot-downs, usually late at night, while LED #7 was glowing. After pulling out my RAM DIMMS and reinstalling them, I noticed that 1. As long as I left my Mac on for days, w/o a restart, it would run quite stable. 2. Once I have to restart, as long as I ZAP the PRAM, 3-4 times per restart, my Mac would run OK. I got the "Apple Service Diagnostics Dual Boot" disc, v. 2.6.3 that fits my G5 model. I ran it twice, once as a single loop (always "continue on error"), which took couple hours and PASSED. The 2nd time I put it to run for 5 hours. I checked the monitor from time to time, and all the "result" (?) lines in the Log were green. After about 5 hours I noticed LED #7 glowing again, and the screen was frozen, see below. ...So at least I did not get any error messages... What you guys thinking?
