Fujitsu-Siemens Gaming Notebook - Bad luck or production issues?

Hello everybody,

I'd like to share a story, which is in fact my laptop's awful history..

About 1 year and half ago I bought a brand new Fujitsu Siemens Amilo M3438G notebook (Pentium M 760, 1GB RAM, GeForce 6800 - 256MB, 2 x HDD 100GB, 17"display....). Very nice model, good pricing at that time, so I decided to buy it as a desktop replacement, since I'm constantly travelling back and forth between my home and the town where I'm studying.
All went fine 'till 3 weeks after my warranty expired, when i got all of a sudden a blue screen in XP caused by "nv4cpl" and my laptop froze. When I restarted, the display showed odd vertical red, blue and green patterns. I googled this asap on another computer, and found several others with similar problems. The videocard died...
I went to the FujitsuSiemens service, and had to pay 300EUR for a bloddy new GeForce 6800. Thing is, a few days ago (new card came about a month ago) when I decided to play a 3D game, my new videocard decided it's time to die. And so she did...
I am appaled by this situation, I would rather throw the notebook out the window, but i still need it. The service couldn't offer me any clarification on what is wrong with my system. All they said was "we'll order a new videocard, must have been a production fault" (luckily i don't have to pay for the 2nd one, because it's still under warranty), but i'm smelling a faulty motherboard.

If someone has any advice, suggestions, I'd be very happy to read them. As a clue (I told service too) I noticed that before all of this started, my processor voltage was around 1,2V normal operation and 0,9V in Quiet Mode. After they replaced my card, It ran constantly at 0,99V, no matter what, but no performance changes or anything noticeable.

P.S. My laptop had a nice life, always clean, no fan blockage, no dust, no hits, no overheating in any way...

Thank you,
Cristian
