Hi All, odd problem here... I have a power pc and recently installed some new RAM. All worked fine for a few weeks then the computer randomly shut down. I would turn it back on and it would chime but shut down again before it was finished booting. Thinking this was the new RAM I took it out and rebooted. All was fine. To cut a long story short, I now get this problem with any configuration of old RAM and/or new RAM and to allow the computer to boot successfully I have to at least take out a RAM card and then put it back where it came from... It seems though the new RAM did trigger something but this now happens no matter what RAM is in there. Also, taking RAM out seems to reset something that makes it start up OK. Any ideas what could could causing this..? many thanks Jay.
