Hi Bruce, My board does not max out at 8GB, that is only if running at 32, I am running at 64 which means I can increase ram very high. I will disable 4GB anyway and try it. I did it this morning and I had to restart my computer 5 times to get it to stop crashing. Yesterday, I also tried copying the Windows Explorer file from Windows folder to System32 folder, which was advised by Microsoft forum, It did not work.
ps. By the way, I built my computer so I don't have a problem working on it.
