If it's a RAM issue, try to clean the part which is connected to the motherboard with a pencil eraser. Simple yet effective.
Believe it or not, I just did it before I post this comment.
If it's still not resolved yet, try using a single piece of RAM first and see how it turns out. If using 1 stick of RAM resolves your issue, while using the other recreates it, then you've found the cause of your problem.
