PLEASE HELP! Big trouble with D630 and Nvidia Quadro NVS 135m

Hi, I wonder if someone could be as kind as to help me with this. My laptop is a D630 with Windows Vista 32 which otherwise was working perfectly.

First the facts:
-Starting last week, my screen started to switch off without apparent reason requiring a hard reboot each time it happened since nothing else worked to bring it back to life.
-Then it started getting worse, one of the times I rebooted I got a split screen (two identical bad quality images one on top of the other) and the only way I managed to get out of it was to disable the nvidia driver (I had already tried to revert to the previous one and it was failing as well). Only problem with that is that playing video with the Nvidia disabled is a nightmare since the image slows down a lot and it's not synchronized with the sound.
-I tried to install the latest drivers from Dell (it seemed to be working then), and then I installed the latest ones from Nvidia and started having problems again.
-At some point during all this, my Windows lost the ability to suspend or hibernate.
-When I thought about restoring the system, it was already too late to go back to before the problem started, since all the available restoring points where more recent than that. (I know, slow reflexes on my part). I still tried to restore to when the new Dell drivers were working but the restoring failed (several times).
-Once or twice I managed to re-enable the driver and make it work for a few hours but the "screen turn off" eventually appears again.

Now the questions:
-Does anyone have a solution for this?
-Has it happened to anyone else? I searched D630 and Nvidia in the forums but all the threads I found were from 2008 and older.
-What's the next step, what should I do now?
-Would re-installing Windows be the only option, or it wouldn't help at all since I'd still have a driver problem?

Thanks so much for your help, I'm going nuts with this...

D630 = Late 07 onwards? In which case it should be under warranty?

In which case talk to Dell - it either needs a guided reinstall of the drivers (i.e. You're doing something wrong) / guided restore, or there is something wrong with the GPU.

 

Thaks for your quick answer, Vogelbung.

The laptop was bought in February 08 in Spain. I read somewhere that it's the card's problem and that Dell had issued a worldwide extended guarantee to replace them. I'm trying to contact Dell in Spain now but the problem is that right now and until the end of May I live in Switzerland and that's why I was trying to solve this on my own...

 

Cover should be Europe-wide. Including Switzerland.

 

Let's hope you're right... In the meantime, I'm open to suggestions if anyone else has an idea

 

The corrupted display does appear to be the nVidia GPU problem. The warranty extension details are here. However, if you got a 3 year warranty for your D630 then you will still be covered by that.

Dell's warranty should work even if you are away from home. They just look in the database to see the warranty coverage. You can also check for yourself you by entering the D630's service tag into the Dell support site.
