[QUOTE="adrian.bryant, post: 710004, member: 63752"] Hello, Thanks for replying. The mac shuts down after several hours use. I think you are right that it is either an overheating issue or power supply. If I leave the iMac for say 5-10 minutes I can power it up again, and it works normally. So I think overheating is a strong possibility. When it turns itself off it briefly makes an unusual sound, after shut down. It sounds a little like Captain Kirk beaming down from the Starship Enterprise. Maybe he's stuck inside and that's the problem!!! The monitor screen has developed a slight tick every so often too. I am not using a UPS or surge protector. [/QUOTE]
