You have a dozen or so drivers from Dell.com to install. Use your service tag to get them. Nothing is wrong after a W10 reset here. But many forget that a reset means we have a lot of work ahead of us.
Its lagging when I scroll up and down in my steam library even. I've got an old Alienware m15x, and the last time I cleaned it was only 2-3 months ago so I don't think it's the fans. I'm running Windows 10 and I just reset it, and still nothing (although for some reason it didn't get rid of a lot of my things). Someone pls help, I want to play video games and it's extremely frustrating (Sorry if this isn't the right place, its the first thing that came up when I searched "computer help forum")
