Unfortunately, since you've given us no information about your computer, (make and model, laptop or desktop, operating system used, etc.), this is about the best option one could give at this point.
Hope this helps.
So plugged my headphones in it said i should configure due to audio playback being enabled, as soon as i pressed enter, got blue screen/no signal range, and no i cannot boot my PC up normally, without having to go on safe mode first then restarting to get normal boot up, my resolution is normally 1360 x 768 now when i boot it up in normal doing the method i have to do, My resolution is still 1360 x 768 but my desktop isn't scaling so my icons are not fitting fully onto the screen. And i also get the no signal when i load up Dota 2 after the launch bit. What should i do?
