My computer kept disconnecting from the internet and as I was trying to connect back to the internet, everything just kind of became unresponsive. My computer restarted and booted up and got past the hp logo but got stuck on a black screen with the white dots on the bottom of the screen circling around to indicate that it's loading. It probably stayed on this screen for an hours. I restarted my computer several times to see if anything was different but it just keeps getting stuck at that screen. What's going on?
