MartenKL is correct, you will need/want to reload your OS to a fresh partition, load the drivers from the disk that shipped with the MOBO (uncheck the power saver, and do the automatic install - that way it will be sequenced correctly - some drivers need other drivers to be loaded previously, to enable 'dicovery' of the hardware - it will reboot several times during this process...)and then restore your data from backups (you do have backups?) - might be a good time for the switch to Windows 7 - you'll never go back to Vista!
