computer does not boot after colors faded

[Lightbold]

Hi everybody,
a friend of mine has a big problem. He was working with his laptop when suddenly all colors faded and the computer shut down. After that the computer did not boot anymore.
He uses Windows XP if that should be of interest.
One time it startet to boot and came until the screen where you have the windows logo and it's loading,
but then he had a blue screen talking about a problem with his nv4 device.
In the other cases the computer does not boot at all, but shoes a grey screen with a few colored vertical stripes.

I have no idea what exactly the problem is other than that it is not a software problem.
Is it the graphic ship?
Or do you think it is the mainboard because I mean one time you suddenly say the windows logo which needs a graphic ship or am I wrong?

Hope you can help me here.

I think you mean Graphics Card or Chipset, which I think may be the problem here.

What model number is this laptop?

How old is it?

What was he doing when it cut out?

[Lightbold]

I don't know the model number of the laptop, but it's maybe a year old
and he was playing an online game and checking emails.
The game doesn't require a lot so it shouldn't be the problem of overheating.
The computer brand is Medion. It's a German company.
The graphic card is probably on board.
Hope that helps you a little.

There should be a model number somewhere on the laptop, either written on its case or on a sticker somewhere (usually on the bottom).

Does it have warranty?

And, just for the heck of it, can you boot in Safe Mode?

[Lightbold]

I will ask for the model number. Don't have the laptop here with me, but since it's not booting anymore at all there is no way to boot it in safe mode. I am not sure about the warranty.
And what exactly do you need the model number for?

[Carbon Dudeoxide]

With the model number, I can help you determine whether or not your computer is still under warrenty, help you get in contact with the manufacturer's customer support, and/or see if this is a problem with the type of laptop.
It also helps give us an idea of what we're working with.

Did you try?
Are there any lights on laptop's keyboard? Can you hear any fans running?
