Today I found this very strange error message while booting my system. I already installed the actual BIOS for my motherboard, a Gigabyte GA-M55-S3 v2.0. I remembered that Vista installed several updates (46) when I left the office yesterday. That must be the cause of the problem! While talking to my colleague we found the solution, it has something to do with DMI. I never thought about what DMI is and what it does. Nevertheless the Gigabyte BIOS has a tiny tool called "Flash utility" (or similar), you can reach while pressing the "End" key when the system boots. There is an option for "Keep DMI Data", this was set to "Enable" – I turned it to "Disable" and then the system booted fine.
