|Try this |
* Contol Panel
* Performance and Maintenance
* Administrative Tools
* Smart Card( check if its active and started manually)
* If not click twice and start it ,then click ok.
* Reboot your computer (I shut it down holding the main button in for a few sec)
If thats ok, remove the cables from the motherboard. Boot the pc, shutdown, reconnect the cables & reboot.
