I posted this same topic a while back, but I am getting the 'This copy of win is not genuine' black screen again. I built my computer and bought win 7 home premium on line from Microsoft. I received two disks in the mail and installed 64 bit version.
I activated and was fine for a few months and got the black screen. I am deaf. My wife called Microsoft on the phone and got it straightened out for me.
This time, I added a usb drive to my comp. and got the black screen. I removed the usb device but the deed was done.
My wife is out of town for two months and I have no one here to call Microsoft on the phone. I can't find the activation code so I can't activate on line. I have been through all the activation tutorials.
Surely Microsoft has some way of handling my problem on line.
