This has been an issue for a few days now. It seems to only happen when my PC comes out of hibernation. It does not do it when I'm actually using the PC, only at random during PC hibernation. I will post my most recent Minidump file. I have an HP e9150t with 6GB RAM, Windows 7 64-bit, Nvidia GeForce GT 220, and an Intel i7 920 CPU.
