First off, I'd like to thank everyone for their help last time with this issue. I thought my problem was fixed . . . but it's not. I have a RAM problem; everyone here at MacRumors sai the 3rd party 512 MB chip that ClubMac gave me free was faulty. It caused me to have an inordinate amount of kernel panics after waking up from sleep. I took it out (leaving only 256 MB in) and I had not one kernel panic-for one entire week. When I put the 512 stick back in, I had a kernel panic the first time awaking from sleep. I called ClubMac, they were very helpful, and sent me another 512 stick. I put it in, and it seemed to work great. My Powermac would wake up fine from sleep-or so I thought. For the last 4 days, I have had a kernel panic after a long sleep period. Only sometimes though. Try to follow this. A sleep from 10:00 PM until 7:00 AM results in no kernel panic. A sleep from 7:00 AM until 6:00 PM results in a kernel panic. This has happened 4 days in a row. I am sure it will happen again tomorrow. Is this RAM also faulty too? Or is it my computer having problems with long sleep periods. Is there even a difference between a 9 hour sleep and a 11 hour sleep besides the nominal 2 hours? Everyone helped me so much last time, and I need assistance again. Thank you.
