Question / Help OBS won't start stream?

I've been having issues trying to stream with OBS, I haven't touched any of the preset settings since it's been a year or so since I last streamed on Picarto. When I click "Start Streaming", a moment later a box pops up saying "Starting the output failed. Please check the log for details. Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date."

This is a new laptop, and I haven't been able to install the update for version 1709 for Windows 10 [ it keeps freezing at 88% ]. I'm hoping this doesn't mean my drivers are unfixable or something along those lines.

I uninstalled and re-installed and have the latest OBS version from the website, so the program should be up to date. [ Version 20.1.1 ]

Here are the most recent logs:

That log doesn't have an attempt to stream. Can you open OBS, click start streaming and cause the error, and then Help -> Log Files -> Upload Current Log and link here?

Looks like your mobile GPU does not support NVENC. You will need to use another encoder.

If you used NVENC previously on that laptop, then do as the message states and make sure that your GPU drivers are fully up to date. Check the website, don't rely on automatic updates.

Fenrir, I also have been experiencing these problems. Even after updating my NVIDIA Geforce drivers, plus my video drivers it fails to work. I have never used NVENC and I don't know if this is affecting the stream. If it is how do i get NVENC? This is all very new to me so I might not be able to comprehend what you tell me but, if you have any thoughts or comments i'd love to hear them.

Here is the code.

If you're not trying to use NVENC, then change the encoder back to x264 or Hardware QSV in Settings -> Output.
