Mac keeps asking to be restarted.

by d_manu / December 1, 2009 12:40 PM PST

For some reason for the last day or 2, my imac screen will be filled with a shaded transparent screen with a message saying something along the lines that i must restart my computer. my system is the Mac OS X leopard 10.5.8.
It will happen at random times, sometimes it will take an hour, sometimes couple of minutes. Most times it happenes right when i click on say a file or a link or anything. But still happens when nothing is clicked or anything.
Any ideas whats going on? anyone had this problem?
Any feedback will be much appreciated.

cheers dan

Have you installed anything new in there, like RAM?

RAM is one of the major causes of this screen.

Lacking details as to what Mac you have does not help the troubleshooting process.

If you installed 3rd party RAM, remove it and put the original back in.

Is your Mac still under warranty? Judging from the processor, it must be pretty new. I have been through an increasing number of kernal panics, at irregular intervals, in the past. Unfortunately, my machine needed to go into the shop and have the logic board replaced. Apple did this repair under my Apple Care warranty.

If the behavior persists, you may want to try reinstalling the operating system. That was one of the first fixes that the Apple tech had me try. Be sure to back up your hard drive before you start this operation. If you have been using Time Machine, click on the icon and make sure that you have a few recent backups, then put the OSX disc into your machine and follow the on-screen prompts. Good luck!
