Sony vaio VGN-NR31Z screen problem

[Hozra1]

Hi!
I could not find any thread similar to my problem so please help!

I have a sony vaio laptop with the nr VGN-NR31Z that i upgraded to windows 7 x64 around a week ago. And it worked without any problems. A few days ago while I was using the computer the screen started to blinck a few times and then it completley turned black.
Now when i start the computer I can see a light is going on and I can hear from the sounds that the computer is booting normally.
I have tried to do all the things that i can do such as using onother ram to se i it is a ram problem and i have used a flash light to se if I can se anying but nothing is visible.

Any suggestions on what it can be and how i can fix it?
Thanks

hi,

the RAM isn't the problem if your pc is booting normally and you hear Windows sound.. If you tried all, the possibilities are 2:

- laptop's screen is broken
- laptop's GPU is broken

to test what is broken, try to connect your laptop to an external display. If it works, your GPU is fine and your laptop's screen should be the problem...
