Whilst seeking answers to my on-going BSOD problem, I found Tech Spot. I wasn't previously aware that there were so many people willing to help others and it is my privilage to join and learn from you. Thank you in advance for your help. By the way, I am convinced my BSOD is being caused by some kind of incompatibility in the old RAM department, but will leave that for another thread. Until then, all the best to you.
