So about a month ago whenever I boot my pc instead of the Windows 8.1 boot animation with the blue logo, it instead both of my monitors flicker black and grey continuously. My pc still boots up fine but I'm wondering if this could be the start of something, I've looked into it and couldn't find much on the subject.

Another problem I have is the login sound effect being delayed when I login, I have checked to make sure window sound is set to automatic.

Thank you for the help.
