Blue screen afer new installation

Medion laptop about 4 years old. It has Nvidea Geforce 9300 m. I don't know if it is onboard or a card.
It had vista and ran fine for 4 years then the graphics went crazy.
After roll back of the driver it would work on with standard graphics, install the driver and it would not work.
So we installed windows 7 premium. It went ok for 5 days then blue screened.
I rolled back the driver and it was ok. Reinstalled the driver and blue screened again.
The driver i got from nvidea.
What do we do now?
Anyone know if it has a card or onboard video?

Most laptops have the video adapter on the mainboard. It is possible that due to dust buildup or other heat issues the adapter is overheating when used with the correct drivers. Check for dust and to make sure that any fans are runnning. You could also try a temperature monitor program like SpeedFan to check the temperatures.

If you can give us the exact model number of the laptop it would be helpful.
