I bought a PowerMac G4 Dual 1.42Ghz as a Christmas gift for my brother's family, who had just lost a Windows machine to a short. They do not have the money to buy a new computer, and this looked like a nice, $100 deal that could at the least get them time until they can afford something else. (And a cheap way to introduce them to a Mac) PM arrived here, I intended to set up accounts for each family member and move their old music/photos from the Windows HD that I was able to save. The problem is that the PM is freezing up on me, three times in two days in very limited time on. Last night it froze twice while simply browsing the web. It just froze, wouldn't respond, I had to pull the power plug. Today I decided to use it as my regular Mac for the day and see if anything happened. After a few hours I decided to watch a Tron trailer in Quicktime that I had downloaded. It played halfway and then froze again. I can understand a problem with video on an older Mac but the first two times it was simply on normal webpages. Temps on the CPU are running 48-55 degrees Celsius. Even before the last lockup with the movie trailer I checked the temp with iStat and it was 55 as it was playing. I closed the dashboard, went back to the video and it froze. Another issue I'm having, not sure if it's related, is the power button takes 3-5 pushes to get the Mac to turn on. Does this sound like the dreaded power supply problem? How about the power button - is that the power switch having problems? I picked this up for $100, I don't have more cash to put into it, but I can't give this as a belated gift in the condition it's currently in. It's running 10.5.8, has 2GB of RAM, the main HD is 380GB, plus another 380GB HD and a 120GB HD. Anyone have any ideas or suggestions on what to do? Should I look into resetting the PRAM and VRAM? I'm not familiar with those but I see that as a common answer offered up on the forum to power supply problems. Thanks for your help.
