The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Apple G5 Reinstall OSX on new Hard Drive - Possibly Overheating

Asked by FASTECHS in Apple Desktop, Apple Hardware, Apple

I am helping a friend with his G5 before as he says he uses it for firewood.

The problem is that it randomly turns off. If you hit the keyboard it goes right back to where you were. Sometimes you can run it for hours even days and it is find. Then it will then just randomly restart.

My friend has had the motherboard replaced as well as the power supply  same problem.

We tried safe boot, yet the ical and imail programs would still start. Not sure why these wont go away because when we terminate them they come back.

We tried running applejack. It actually completed without any reboots or freeze ups!!! This made me think well maybe it was something messed up with the os because no sooner than we rebooted after a full scan with applejack and no problems, the system went back into os x and did the same exact thing.

I thought well lets try installing a fresh version of mac os 10.3 on a brand new Seagate 1 TB sata hard drive. I got his black cds and put them in. I held down the c key. However I cant figure out how to get it to install. The hard drive has nothing on it and was brand new sealed.

At this point I believe it is either an overheating issue, thermal sensor that is messed up, or bad os installation.  

Reasons I think it could be overheating  when I have a large fan blowing, the unit seems to run better. Also please see attached photo, but the two fans in the lower left corner spin, but there is a duct with a silver heat spreader that gets REALLY and I mean REALLY hot. It is so hot at times you could easily cook breakfast on it.

Reasons I think it could be an OS  I cant seem to get ical and imail programs to stop running. Even in safe boot I would close and they would just reopen in like an endless cycle!

My questions are, what are your thoughts?
Are these sensors easily replaceable?
Whats the trick to install OS 10.3 on this new drive?
