I've been running Windows 10 on my Dell desktop for a few months now with no major issues. Now, it decides to randomly act up. Anyhow...

The computer boots up to the login screen where it shows the picture. Once I hit a key it shows the user name and the password box for a split second, then the screen goes black with a moving cursor only. After about a minute the "picture" comes back and the same thing will happen again if I hit a key. Any ideas? Thanks for any help you can provide!
