I have a Razer blade stealth. I begun having an issue shortly after receiving my stealth. The computer would hang randomly and require a hard reboot. Sometimes while browsing the web, sometimes while transferring files, sometimes while just sitting on my desk. The point is there was no common denominator. I called razer tech support. They couldn't figure it out and authorized an RMA. After my new stealth arrived, same thing happened. So I read on a few other forums that people made changes to their registry and we're having similar issues. Computer randomly freezes, or when you open it, the keyboard lights up but the screen remains blank. My registry change was the PreferExternalManifest change that allowed programs to scale properly on the high dpi razer displays. I deleted this addition and it has been running smoother ...cross your fingers... But has anyone else been having similar problems? I need this computer to work, and I need it to last.
