Windows 8 Win 8.1 turns purple

[jmf1964]

If I leave my computer alone the screen will turn blank purple after a few minutes and no amount of keystrokes or mouse movement will bring it back. I have to let it sit until the screen saver comes on then it'll wake up normally. The computer boots to windows with no problems and otherwise works well.
Anyone have a fix for the blank purple screen ?

It could be the lock screen but you can override the settings so that it doesn't kick in or at least doesn't need a password to unlock
