My imac's screen keeps going to sleep randomly... sometime frequently other times with extended intervals...
I have checked forums and re set PRAM and SMC also re set the energy saver preferences, turned off hot corner assigned to screen sleep, installed caffeine (non sleep program) but no luck yet... It still keeps happening... Help!
iMac, OS X Mountain Lion (10.8.2), Mid 2011
Get Temperature Monitor to see if it's heat related...

Cool, thanks.
What should I be looking for? Temp on start up in relation to Temp everytime it blanks out?
Those are all acceptable temps, so not the problem unless one or more gets a lot higher.
Open console in Applications>Utilities, check the system log for the date/time of the last problem & the Startup right after that for clues.
This is the latest screenshot, I dont know what any of this means but looks like window server creating sheild?
A bit of a closer shot..
It's far more helpful to post the text of the log than a screen shot... in console highlight the top line you want, then hold shift while clicking on the bottom line you want, CMD+c to copy, then paste in a reply. đ
What does this mean?

Not sure what that message means.
What is 192.168.1.7 on your network? It seems to have trouble connecting to it!???

I think that is the wireless connection?
But to what? A NAS? A PC?
Your guess is as good as mine... probably better.
NAS.. Network attached storage?... icloud?

I'd suspect iCloud, but...
DNS+ Proxy+ SMB
Seems like it's trying contact/mount some Windows thing.
Ok.
It's foreign language to me đ
My flatmate has a PC and a Wireless router connected to an old printer/fax that is connected to our network.
