I have a All in One Pavilion 23 Desktop. I did a Windows 10 update a few days ago and now every time i go to type my computer screen goes black. The computer is still running but the screen blanks out then comes back on after about a minute and all my work is still there. I have finished all updates,a hard drive test,clean the registry. I have checked the Device Manager and everything is up to date. I don't know anything else to do!! Please help!!
