Sounds like you've screwed something up - did you just remove the firmware update? And if so, why, especially if it was working?

Please list in order exactly what you have done, starting with what you last did before your final successful burns. In the meantime post screenshots of your Device Manager window and the yellow flagged devices.

Then it obviously had nothing to do with any firmware update, as System Restore wouldn't have affected that.
