I have a system that will partially start. It gets up to about 1GB of memory, then completely freezes. It detects all the memory I put in, whether it is 8 or 16GB. I have used completely different sticks, could this be a motherboard issue? I have tried using several different OS'es to make sure this is not the issue. The system posts and will start Windows and Linux, but freezes at what I would expect to be about the 1GB mark. Thanks in advance
Considering all the information gathered from the numerous comments. The ideal solution is that your data paths along your mother board arent working like they are supposed to. These data paths I speak allow hardware to "talk" to one another. So if you see those gold lines on your mother board, you'll notice they go from one end to another. Since you stated that since this occurs with your CD Rom as well, RAM would not be a factor if what you stated is that you changed the ram around and your BIOS is i fact detecting the amount of RAM you install.
Look on your MoBo and find the gold lines and trace them all! If you notice bits missing, then take it to a repair store and get it fixed.
I have seen this issue before. Some motherboard makes that have UEFI built in become ruined when you install linux of any bread onto it. Linux has a habbit of making full use of any resources that are available to it. Some UEFI chips tend to freak out when more than 50% of its resources are used up. It's not your ram that's messing things up, it's your UEFI's incompatibility with linux. Unfortunetly, this issue isn't recognized by POST. The only thing you can do now is, hope your warranty is still valid and call them and wrench on them for a new one because they didn't let you add what ever you want on it. It's extremely important to google OS compatibility to any motherboard with UEFI on it as this will cause issues. ALWAYS GOOGLE WHAT YOU'RE DOING EVEN IF YOU KNOW WHAT YOU'RE DOING
