[QUOTE="kevinc5680, post: 918959, member: 17492"] I figured I would continue to update this thread for anyone else who may have a similar problem. So I think I've determined that it is not an overheat issue because I started shutting down my PowerMac when I went to work instead of putting it to sleep. The other day, I came home from work and when I turned on the PowerMac, less than five seconds later it turned off. I tried this three times and the same thing happened. I reset the SMU or VMU, whatever that button is and it worked fine. So I started playing back everything in my head since I got this computer a few months back. For the first month/month and a half, I never had a problem. I would play video games on it for hours at a time and no overheating, no shut offs. Then the random power downs started. What did I do differently? Well after going over everything, I determined the only thing I changed was from my Apple keyboard to a Microsoft keyboard. I did this because the cord was longer and easier for me to have the keyboard at longer lengths from the tower (obviously). Well since I've used this keyboard, I've had the power down issues. Four days ago, I switched back to the apple keyboard and I have not had one issue. This is probably the longest the system has gone without a crash since I started having the issue. Could this be the problem or coincidence? [/QUOTE]
