finished update and rebooted to get nothing but a blue screen... after a few restarts it finally booted up but now have no internet access. I upload using my desktop which is hooked to a modem with 2 laptops hooked up using wireless. the laptops are working fine but desktop is a no go. Tried new wires, different ports, restarts, and modem reset. dont know much bout this so any help would be greatly appreciated!!
