Hello !
I was surfing around YouTube and my laptop screen suddenly started flickering and few seconds later my laptop turned off. When i opend my laptop again every thing was okey for 10 minutes and then it happend again but that time it did not turn off. Is it a software issue or hardware one? I have the latest video drivers so that is not the issue I think. I have done AIDA64 stress test as well. When I was doing it I got the TdrDelay warning message. Maybe that is related to the problem. Here a image as well.

It could also be the display or the connecting cable. Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
