Graphics card problem

Hi all , well i'm new here and this is my first post. I have Nvidia GeForce 9500 GT installed on my computer. Recently i upgraded my driver from 295.73 to 306.97 and from then every few minutes my computer display goes black, then turns back on again with a notification saying something like :
nvidia windows kernel mode driver 306.97 stopped responding and has successfully recovered

I uninstalled the drivers and again installed my previous version (295.73) but the problem still persists. I'm using windows 7 professional.

My complete system specs (checked using everest ultimate edition) are :

  1. In my experience the "driver stopped responding but sucessfully recovered" is an error related to faulty video memory. I would download video memory stress test, which is kinda like memtest but for vram and let it run for a few passes. If it fails you have bad vram, if it passes you can move onto another troubleshooting step. Always have to check the hardware first, software cannot fix bad hardware.

  2. A friend of mine has been having this very same problem for quite a while now, and I spent a considerable amount of time searching for a solution or clues that might lead me to one. Tried different drivers, but nothing seemed to make a difference.
    Today, the system started failing right at start-up, and it was obvious that it was due to graphics board malfunction. So, I decided to extract it from the system and take a closer look at it. Unscrewed the heat-sink, and straight away realized that the thermal paste was completely dried out and definitely not doing its job. So, I scraped off and cleaned out all the old paste, and replaced it with a new thin layer of new paste. Took the opportunity to clean out the heat-sink and fan, and set everything up again neatly. After re-installing the board back in place, re-started the system, and to my great surprise, the system suddenly became completely normal and stable. Has been now, for a few hours, after stress tests with intensive graphics applications and games. After all this, it occurs to me that the problem may in fact be due to overheating of the graphics processor, and the defective dissipation of the heat produced.
    So here's the suggestion: take some time to look at the hardware instead of the software. Make sure that you have a good heat transference between the surface of the graphics processor and the heat-sink. Might save you some time and a lot of headaches. It might be as simple as this... Give it a try...
