Some motherboards are very choosy when it comes to using more than one stick of ram. Some of them don't like a mis-match of brand, while some don't even like a mis-match of ram specifications even when same brand. I had endless problems like that. In the end I bought two identical 512MB sticks at the same time, threw out the one I already had and those two work just fine.

So, yes, having two sticks same brand should cure your problem but they might also need to be exact same spec. That's why I bought two matching sticks at same time. I wasn't going to take any more chances of them still not working together.
