Bug Report Sudden D3D10 Error -- streamed fine before

Hi, I'm having the fairly common D3D10 error:

"Could not create D3D10 device and swap chain. This error can happen for one of the following reasons:

1.) Your GPU is not supported (DirectX 10 support is required - many integrated laptop GPUs do not support DX10)
2.) You're running Windows Vista without the "Platform Update"
3.) Your video card drivers are out of date"

I've streamed with OBS for several months without issues. Following a reboot earlier tonight (done immediately after streaming for about 30 minutes successfully), I suddenly received this error and can't seem to find a solution. Because I have streamed before, I KNOW that none of these listed reasons affect me, so it is likely some setting got changed on my computer. I have no idea what setting, however. If it is relevant, I have a ~3 year old HP laptop and an Intel(R) HD Graphics card. I've read on the forums that these graphics cards are generally incompatible with OBS, but again, it has worked flawlessly many times before. I haven't even updated OBS recently, either, so I am clueless as to what the issue may be. Thanks for reading and I hope someone can help. :)

If you've been using that same computer and have been streaming with OBS successfully before then something must have changed on your computer, such as drivers or device changes. You may want to install latest drivers for your video card and such. If it's a multi-GPU laptop you may want to make sure it's streaming using the correct GPU via nvidia/amd control panel settings.

Strangely enough, it fixed itself after another reboot. I'm pretty sure one of my display adapters wasn't even showing up in my device list for whatever reason. Thanks for the help!
