I almost always leave my iMac on overnight, and after a time it goes to "sleep." When I tried to "wake" it this morning, it wouldn't restart. After shutting it off and restarting, I had major problems when it rebooted -- it would freeze up and the screen would go (for want of a better word) fuzzy. After four or five reboots, it seemed to be ok, but it went to sleep again later this morning, and the screen went fuzzy again for a brief moment when I restarted it.
anyone have a clue what's going on here? |

I've had problems with "waking up" my iMac (1998 machine running OS 9), as well. Generally, I can reset the computer or unplug it to get it to re-boot, but if I had applications open when it went to sleep I may have problems with those applications. I find it useful to run Norton Disk Doctor after re-booting or if the system ever freezes. Norton is great at cleaning things up and making things work well. I don't understand why it sometimes wakes up and sometimes doesn't. I'm now in the habit of closing applications each night. |

Slowly the truth emerges. Mac's have problems, too.  |

This has been discussed previously, but I never leave my '98 IMac on. I turn it off each time I stop working. So far, have never had a problem starting up. What's the definitive answer to the question?

Turned out the problem was one of the midplane components. Apple sent me new RAM and a new midplane, and I replaced the RAM first and didn't solve the problem. That meant removing everything -- hard drive, optical drive, power supply, etc. and replacing the midplane, which contains the processor and other vital components (which frankly, I couldn't tell you what they are). Everything now works fine, although the new fan seems a little louder than the old one.
Kind of fascinating to take a computer apart and put it back together. The iMac is designed for a user to be able to replace virtually any part with just a phillips screwdriver. |
