hey bud.. that only happened to me twice... so just sharing my experiences...
1.) it happens during server maintenance... or if they are doing a quick check of the server (without notice)... this happened to me twice... yours is for frequent, but as i said, just sharing what happened to me
2.) the video card drivers needs to be updated... the screenshot you took list the build, etc... of the video card... after updating the driver in my case, it was no longer listed and then worked fine... so you may try updating the driver... i updated mine not 2 weeks ago and thought i was completely updated but the fact was, i checked again and there was a new release...
obviously #1 doesn't help you, but hopefully #2 will...
