My iMac started to randomly go to sleep last night. I reset the SMC and it stopped last night. Now today it has begin again. I just reset the SMC so we'll see how it goes. Does anybody else know about this problem? I bought my iMac in 2010, it's an i7. I don't have applecare.

Well it's no longer doing this and I've gone a full day without it happening. I'm not sure if it's related or not but during the 24 hours that it was happening we had a wind storm (50mph gusts). The electric never went out, but I wonder if it could have been from a power surge.
This has started again today after not doing it for 2 1/2 weeks. It's randomly gone to sleep while I've been using it 3 times today. Below are the errors in my log, do you notice anything?
