NVidia GeForce 7950GT Graphics card driver error

I am using Windows Vista with an NVidia GeForce 7950GT graphics card. When I switch the pc on a whole host of dotted, coloured lines appear on the screen and then I get the blue screen of death which then restarts the pc and the whole rigmarole goes on! I get a 'solution' from Microsoft suggesting that the problem is with the graphics card and I should update the driver. I have done this but the problem is still occurring. I have also done a system restore which has also made no difference.

I managed to look at the error message.  It said that an attempt to reset display driver and recover from timeout failed and to check any new hardware or software was properly installed. I haven't installed anything so this can't be the problem. The technical details are as follows:

STOP: 0x00000116 (0x8FF8F510, 0x8C2E4326, 0x00000000, 0x00000002)

nv1ddmkm.sys - Address 8C2E4326 base at 8C206000, Datestamp 4c379162

Does this make any sense?

I had some advice which was found on the Wiki-errors website as follows:

Novice Computer User Solution (completely automated):

1) Download (0x00000116) repair utility.

2) Install program and click Scan button.

3) Click the Fix Errors button when scan is completed.

4) Restart your computer.

I install the program and scan my computer and it came up with over 2000 errors. I clicked on Fix Errors but it needed a licence key but when I clicked on the button to obtain this, nothing happened so I can't go any further with this.

I hope you will be able to help me as I'm running out of patience!

I look forward to hearing from you soon.
Kind regards

My first suspicion is that your video card has overheated and may be toast.  A common failure mode is that the card will run in VGA mode but as soon as it switches on its full capabilities, it shuts down.

Is the video card fan running at full speed?  Is the heatsink clogged with dust?  Clean up the video card airpath and while you're at it, check for any swollen capacitors on the video card (see http://en.wikipedia.org/wiki/Capacitor_plague).  Then try again.

If you get a BSOD as soon as you boot up, then how did you manage to install and run the scanner program?

After the BDOD the pc restarts & I can go into Safe Mode.

I have cleaned all the fans inside the pc and it does seem to be quieter. I couldn't see any damage on the graphics card. However, the problem still exists and I'm having to go into Safe Mode to do anything. Have you any other suggestions please? Thanks for your time.

Great advice although it didn't completely solve the problem.
