My Dell Latitude shuts off unexpectedly when going to sleep

I have a Dell Latitude with windows 7 and an core i5. It shuts down unexpectedly when I close the lid to put it to sleep and when I press the sleep button. This has been happening since monday 11/25/2013 around 5:30 pm. I scanned the whole computer multiple times using Kaspersky 2013 and it didn't detect any threats. I used system restore and it shut down unexpectedly again a few times untill I was able to somewhat restore it back but it shown me a message stating that it did not successfully restore. It detected 10 updates. I ran the update but the problem still persists. I was able to get this statement when it recovered:
