On startup a white line displays in the left corner. Please help!

[Stuka_Hunter]

This problem occured after i updated my Windows 8.1 computer with some smaller updates today. As it stated after the updates that a computer restart was needed, i restarted it acordingly. After that this problem occued. I tried everything i could find, from deafulting UEFI settings to using the Windows CD to run the diagnostics, but nothing worked. I have no idea what is the cause of the problem or how to fix it.

Any answer is appreciated. Please reply, I posted on 5 different forums with no replies.

Kind regards.

Is it a very small line?

3 of my 6 PC's have it.

Does it still boot to windows after the little cursor flashing?

Its a small white blinking line, yes. About half a centimeter long.

No it doesnt boot at all. Its just blinking forever.

Make sure in the BIOS your boot drive is selected.

I tried booting from 4 different sources and not one worked.

Try both solutions above.

I tried from the exact video you sent. It did not work.

It also sais that I can "refresh" my computer once I put in the CD, but it sais that computer has to be unlocked and this feature doesnt work.
