First and foremost, thank you for your help...it is very much appreciated!
So, according to your reply, am I to assume that extended memory is in the RAM? Perhaps you thought I was referring to expanded memory?
One troubleshoot I tried was I removed my RAM sticks one at a time and the problem remained regardless of the stick and/or sticks that remained slotted.
On another note, I read somewhere that on a DDR board, the color slots had to house the same type of RAM, which was not a problem for me since they are all the same make, model, and size. Regardless, I tried it also by pairing the RAM sticks by color slots, two at a time, and still the same issue arose.
I will still look into memtest86+, because I am willing to try anything, however, I suspect that it is not in the RAM. I would really like to know more about extended
memory and where that is physically located. Perhaps I am in over my head!
Again, thank you...I will keep posting my progress.
