Hello there Obs Staff, I was trying to record a video using the NVENC H.264 preset because x264 just lags my video every single time I try to record a video, and it gives me a message,"Starting the output failed. Please check log for details". I downloaded the Geforce Nvidia automatic driver and restarted my computer but it didn't solve the problem and always had gotten this error. PLEASE HELP ME GOOD PEOPLE :(

Intel Quick Sync would be your best bet in regards to performance, your CPU being a straight 4-core would struggle to maintain recording/streaming and game-play as well whilst using x264 encoder.

I would also lower your fps value to 30 for your webcam output, this will reduce the load on your system.

Also,
Game capture grabs the frame directly from the graphics card for OBS to encode before sending it back to the graphics card for final rendering of the frame.
Monitor capture has the graphics card write the frame to system RAM (Which is really slow to write/read from) before OBS grabs it to encode, then sends it back to the graphics card to render for final output.

If you want to use Monitor Capture, you should create a scene for it by itself without any other capture methods included in that scene.
 
You cannot, NVENC encoding is hardware supported, not software. Unfortunately the only way you can use NVENC would be to upgrade your GPU, which given you have a laptop generally means you have to buy a new laptop.
Intel Quick Sync is effectively exactly the same as NVENC/AMD AMF, it is just Intel's version of h264 encoding.
h264 encoding is very efficient when it comes to encoding due to the lack of functionality, it has roughly 1/2 the options of x264 ultrafast preset turned on.
The only way one can really by-pass the lower quality result of h264 is to increase the bitrate, roughly 50000+ it generally becomes nearly indistinguishable in quality from x264 encoding.
To try and negate the quality offset of using h264 encoding at lower bitrates, generally one tries for an extra 500+ bitrate on-top of what they would normally use with x264 encoding.
 
Sorry for the misunderstanding,
Generally Intel either has h, q or t models for laptops/AIO desktops and the majority of people buy laptops.
You may be lucky enough to fit a small form factor GPU in the case, though you would really have to be wary of power consumption and heat output when choosing an upgrade.
 
Replace the card. Generally all-in-ones can't get their GPUs replaced since they're integrated on the main board in a similar manner to laptops.
