    Black screen with flashing line in left top corner when trying to boot windows 10


    Whenever i try to boot my computer i used a windows 10 usb it goes past the bios screen and then goes to a black screen with the flashing line in the top left. I have no idea what to do. Whenever i go into bios the computer sees my ssd. Ive even hooked it up to my other computer to make sure it wasnt my ssd. All help is appreciated.

    Windows 10 download blank screen on laptop with curser flashing top left corner.

    I downloaded windows 10 to HP laptop620. Took about 7 hours. Ended up with black screen with curser flashing top left corner, nothing else. Each time I start that's all I get.

    black screen with blinking line in upper left corner


    Sorry.
    I do not have any windows 10 disk. I got windows 10 as a free download/upgrade.
    My pc does start up, meaning: black screen with some start up informations as it always has done. After a short period, I have black screen with blinking line (Cursor?) at upper left corner.
    Thanks for your assistance.
    Best regards, John

    Flashing black box in upper left corner

    Immediately after upgrading to Windows 10 I have experienced the appearance of a flashing black box in the upper left corner of the screen. It seems to appear about once to several times a minute and is extremely annoying to the point I 'm considering
    going back to Windows 8.1. It flashes on and off quickly. The Microsoft representative told me to be patient and he assured me there will be an update soon to correct these bugs. Has anyone else experienced this momentary flashing black box in the upper left
    corner which appears regardless of what I'm doing? Also can't enable screen saver since Windows 10 download?
