BleepingComputer.com: N Key Problem on Samsung Laptop

Hi,

I own a Samsung Q430, bought summer of 2010. After a couple weeks owning the laptop, my boyfriend and I noticed that every once in a while when typing, the cursor would suddenly move a line up. We eventually figured out that when you press the n key and the space bar key either simultaneously or one after another, it would act as an up arrow key, bringing the cursor one line up. I feel like the problem is only getting worse, as now sometimes when typing words with "n" + "g" + "space" it will bring the cursor a line up as well. Since I can't avoid typing words that end in "n" or "ng", how in the hell do I fix this problem? I can't find anyone else out there that seems to be having this problem, and it's driving me absolutely nuts.

Thanks!
Samantha
