Hello everyone. 2 or 3 months ago my external graphic card is dead on my Toshiba P70-B-11E laptop and Toshiba service changed my motherboard completely. Now i can't install DTS. Even downgraded from Windows 10 to Windows 8.1 but nothing is changed. So i'm not sure what can i do. I can't find anything on Google and YouTube. I searched this problem at this forum and found one topic. The topic owner solved this problem and gave fixing program link but link is dead. He solved this problem to changing OEM String. Like i said, the links are dead and i don't know how can i change this string. Please help me about that problem. Thank you in advance for your help.
