Last night, my iMac started giving me some problems... It boots up fine, but after about 5 minutes it switches itself off! I then have to leave it for quite some time before I can power it back on - I'd guess at more than an hour. If I try to power it on before this point I get no response. It's an Intel iMac, 24" 2.8GHz and, unfortunately, it was bought September 2007 - so it's just out of warranty. Doh!
I'm going to try resetting the SMC tonight, and also try the Apple Hardware Test.
Just to clarify, this isn't a software crash that causes it to stop working, it actually powers itself off. It also doesn't seem to be triggered by any particular activity - I can leave it with nothing running and it will do the same thing.
Any ideas?
Power supply? Maybe a temperature issue? I have iStat Pro running on the dashboard and it doesn't show anything excesive.
Anything I can try before giving up and taking it to Apple
