Are the memory sticks identical in speed and size? With my desktop, I was having issues a couple of weeks ago when I had 2x4GB AND 2x2GB in. They were both DDR3-1600 but my games were running horribly. I pulled out the 2x2GB and s*** was so much faster.
Also, try cleaning it out. I run CCleaner every once in a while to clean out cache, temporary files, history, etc. and it seems to help (maybe it's just all in my head). Is it overheating at all? You might have some dust built up in there that's causing the laptop to stay warmer and not run efficiently.
I run CCLeaner. The 3gb it had stock were all the same speeds, which doesn't make sense to me. I'm convinced it's their s***ty CPU. Like I said, my friend had the same laptop and it did the same thing. They're both 2 gb sticks, however, I think ones 6400 and the other is different, both are DDR2 SDRAM.
