Framerate and bitrate should not be causing this; if for some reason or another your system and/or connection were unable to support 60 FPS and 1700 bitrate, the disconnect or trouble would start a lot sooner.
Reinstalling Windows may solve it but I do not think it likely, hence I will not recommend it. If you are willing to do it, I would understand and in that case I would hope it does indeed solve it. But, again, I do not think it's likely it will. Reinstalling Windows would only end up working if the issue somehow either is related to a misconfiguration of Windows (in which case, again, the stream most likely would not work at all) or is related to malware of some kind. For which there are less extreme methods to get rid of those.
