2 Dell inspiron 15R N5010 laptop not starting up.
I was playing a full HD video on it. Suddenly the screen flickers one or two times and went black. The screen also went to something with green vertical stripes, somewhere in between the flickers. There was also a noise through my headset, which sounded like a motorised woodcutter. The backlight was still on. I tried everything that came to my mind with which could close the application. Nothing seemed to work. So I gave it a few minutes to close the app on its own, but didnt work. Also the harddisk activity light was completely off. I long pressed the power button, turning it off.
When I powered it on again, the power light came on and the activity light stayed on for about 2 seconds and went off. Also during that time the cd drive light blinked twice. No cd were inside it. The screen stayed off (not even the backlight). Then there was nothing. Tried a few button strokes on the wireless keyboard, but nothing happened.
My windows 8.1 audio driver already had some glitches after I installed the google hangouts Chrome app.
Can anyone tell me what could have gone wrong?
I can dissassemble the whole laptop. I've done it 6 mnths ago to change the hdd and to clean up the dirt.
Questa è una buona domanda?

Yes, the computer is with an ATI Mobility Radeon 550v, 1 GB graphics. As with external monitor, I do not have access to the system right now. It is already in the service center. They said the problem is with the graphics and needs to be changed. They said that changing the motherboard is not necessary, just the graphics chip. Could they be true? Is it possible to replace the graphics chip alone? Could it be a simple bios problem for which they are trying to charge extra?
