Windows 7 Problems with Sleeping

The computer goes to Sleep, does not wake up fully, says it is loading windows, goes to black screen indefinitely. I reinstall windows, reset the sleep settings, and then this morning, it comes out of sleep, to black screen again. I restart it using the power button, it loads windows and then BSoD. Should I try reformatting or what?

I won't be able to do that because I cannot load windows. The Blue Screen states that it is shutting down to prevent damage to the disk.
