I got an EVGA gtx 1060 sc for free because it had an issue with it, and I wanted to see if it worked. After installing it, it worked for about 30 miuntes, and I had time to install drivers but no time to do any tests. Then suddenly, the pc just turned off. After that the pc stayed on for about 5 minutes before shutting down, and after that it showed a glitchy mess on my screen and I was forced to turn it off. The last time I tried it wouldn't even post, so I was wondering if anyone knew anything to do with this thing.
