I had just clicked into some video on youtube when the screen suddenly became filled with lines like this:


(This bar is now at the top of my desktop)

(This is my start menu)

I clicked around a few times and it eventually went away. However, my start menu and desktop still has these lines.

Does anyone know what they are and how I can get rid of them?

It could be that the video or graphics card has gone bad or got corrupted in some way.If they are bad they have to be replaced if corrupted try to do a repair and see what happens or try a system restore back to before the problem started.

This can be caused by your graphic card,try updating it and if it still isn't working you will have to upgrade your graphic card to a better one or buy the same one you are using at the moment. Could you tell me your pc specs?

As SUEOHIO and Ryuzaki stated, this is likely due to your graphics card.

Update the drivers for your graphics card by downloading the latest off the manufacturer's website.

Remove and re-seat your graphics card on your motherboard unless your graphics are integrated.

If neither of the above work, replace your graphics card with another card of similar power consumption.

Thanks everyone--it went away after a restart (I was worried it would be something more) but I'll update my graphics card just in case.
