Solved Nvida 8400M GS only working with WDDM

Well done vovven, If it's successfully reflowed it should last , My XPS 1710 suffered the same problem a couple of years or so ago ,So I baked the card and its still going strong
One thing I would advise is running a fan control software to make the fans work harder I personnaly use I8kfanGui Dell Inspiron Inspiron/Latitude/Precision fan control but if you do a search for free fan controllers you will find something to your tastes

I8kfanGui failed to install fano driver i think it was called, maybe it doesn't work with Vostro.

I found fanspeed (SpeedFan - Access temperature sensor in your computer)
First it didn't find any fan it was just showing the temp sensors.
But then i found in configure and options tab a check box has the option "Enable DELL support (use this only for notebooks)" i restarted the program and now it finds the fan.

When you play the game "Left 4 Dead 2" after a while the laptop is getting quite warm and i get a huge fps drop :/

I hope this tool will help to keep the fan speed up so the laptop stays cooler

SpeedFan was no good, it made the system BSOD
I managed to get the I8kfanGui to work in test mode but it made the system lagg when i tried to change fan speeds, "Force high fan speed" or "Automatic temperature control" i could barley move the mouse around it was lagging so hard.

Any other good fan control apps?
