All of a sudden, I'm getting this BSOD every time about 5-10 seconds after loading a profile. Can't start the computer in safe mode; it hangs each time trying to load the drivers (or whatever it's doing). The specific Stop Code is 0x00000051 (0x0000000000000001, 0xFFFFF8A000024010, 0x0000000001DBF000, 0x0000000000000374). Am assuming it could be my HDD (using a Crucial M4 SSD as the boot drive), but not sure how to confirm or what else to investigate. Help?
