I know that it's been asked a while back. I had a similar issue, so I'm posting my solution for whoever else runs into the same issue.
The problem is in your video driver. They coded it without accounting for the system entering the suspended state. Unfortunately it's a common issue with Windows drivers. When they test the driver, some developers don't think about testing it for when your system enters sleep or hibernation. So there's basically a bug in the video driver. (May also happen in any other driver: network card, mouse, keyboard, you name it.)
So the solution is to update the video driver. For that go to the site of the manufacturer of your computer (Dell for instance) and download it from there. (Note that such driver will most certainly not be available via Windows update.)
PS. And no, this is not a Windows issue. It's a hardware vendor who's to blame here.
