Windows 7: BSOD on system sleep

Just 2 days ago, when attempting to go into sleep mode, the screen went black, but the keyboard (laptop controls/hard drive lights) stayed on; like it got stuck trying to go to sleep. Pressing keys/mouse clicks did nothing, so i had to hold the power button to turn it off, and restart it. It then gave me the safe mode question, but i decided to start windows normally. When getting to the desktop, "Windows recovered from an error" and it stated that it was a blue screen issue, though i never saw the bluescreen, of course.



Now every time i try to go in sleep mode, it does the same exact thing. I'm not sure what could have caused this, as nothing significant has been changed in the past 5 days, and the crashing just started 2 days ago.

I hope this is enough information to start with. The BSOD report is zipped and attached.
