Hello Robin and welcome to our forum.
Sorry to hear of the problems you are experiencing with your laptop.
Please find below the answers to your questions:-

1. If I disable the Nvidia graphics, and have it running on the basic VGA grpahics adapter, the computer will sometimes run okay. I assume that this can happen with the Nvidia defect?
Yes, this is quite common and this type of failure is closely followed by a complete failure of the Nvidia GPU.

2. In January 2010 when the laptop was still working I installed Windows 7. Should I try and remove this and revert to Vista in case at some point in the future HP would ask to inspect the laptop themselves as they make clear on their website that they do not support Windows 7 on this model.
I wouldn't bother trying to remove Windows. The fact that HP do not support Windows 7 has nothing whatsoever to do with your current problem so it would be a fruitless exercise for you.

3. I purchased the laptop on my mother's credit card in September 2007 before beginning university. I have, however, sent the intial letter before action in my name (same surname as my mother). Is it okay to continue the proceedings in my name, and then if necessary at some point in the future, I can get my mum to give authorisation for me to continue with the case?
Your mother would have to start the ball rolling against the retailer, or at least give authorisation that they deal with you on her behalf. If this went as far as court then you would have to act as layperson for your mother.
The fact that you paid by credit card is excellent news as the card company is as liable for the failure of your laptop as the retailer. You can make a Section 75 claim against the card company and they have to help.

4. Do you know if the small claims procedure works any differently in Northern Ireland? Also, if I send the laptop to Lapcure for an engineers report (which I expect to do next week) does shipping to and from Northern Ireland with DHL cost anymore?
I am not sure if the court system is the same in Northern Ireland, but I guess it should be.
There is an extra cost of £20 to collect and return to Northern Ireland so the total cost of the report would be £85. This sum is recoverable from the retailer as a consequential loss.
If you have any further questions or if you need any advice then please let me know.
Good luck and best wishes
