Have Vista Ultimate with ASUS SLIC 2.0 and matching cert. Has been going perfect for a long time. Flahsed bios with SLIC 2.1 and Asus again to keep consistency. Win Vista booted up and screen was black saying activation needed. slmgr etck,etc. certificate was accepted and Windows says it is activated BUT screen is black and the left down corner says that is not genuine though is activated !!!!!!! Why did I put SLIC 2.1, because I want to put 7. I am doing this now but do not know what the hell is going to happen. Anyone came to this same problem?
