I reset windows 10 and now my microphone wont work. It registers that I have one but when I go into sound settings there are no green bars showing that it is picking up sound. File transfer is really slow now too. I used to get about 120mb/s for file transfers to my portable hdd and my powered external hdd. It now goes between 15mb/s to 40 mb/s max after resetting windows 10. And the only game I play Terraria keeps crashing on me after 5-20 minutes of playing aswell. First the sound will cut out then anywhere between 1 second to 20 minutes the game will freeze and then close down back to desktop. I went into the games properties (Steam) and done a file validation check and everytime it says 1 file failed to validate and will be reaquired even after a fresh install after resetting windows 10 again. I installed all the drivers I needed after resetting windows 10. Its basicly a new PC only 2 months old. I took it back to where I got it from and they said they will have a look at it. After they went over it. Lucky I didn't have to pay cause when I got it back they said there is nothing wrong. I got it home and checked and the same things are happening.
