I have a home built computer that I installed Ubuntu Gnome 15.10 (64 bit) on the other day. If I have 2 sticks of 1 GB memory, it works fine. If I add another 2 sticks, it won't boot at all but just has a blinking line at the top. I know that Windows XP wouldn't run with over 3 GB but I thought that Ubuntu didn't care how much memory you have. I checked & it says it is the 64 bit version. There isn't anything (that I've found) in the BIOS that would affect this so the question is: what is wrong or what am I doing wrong to make this note use all my 4 GB of memory??? Thanks.

Does it boot with the additional modules instead of the original ones?

+1 and also mixing memory of different kinds or speeds can cause problems as well.

These are all identical sticks of memory. I have tried several different arrangements with the sticks & it is the same no matter which ones I put into it. I have also run Memtest on several different arrangements, all OK. Color me stumped...
