Minecraft lags when I press 'A' and 'S'?

When I'm playing Minecraft on my PC, it will start lagging slightly when I press 'A' and a lot when I press 'S'. This happens halfway through gameplay (2-20 minutes) and I have only had them problem on a survival/hardcore world. When I press one of the keys, the whole world will quickly flash as if the chunks are re-loading. Can anyone tell me why this problem occurs or how I can potentially fix it?

Budget Laptop that will run Rome 2: Total War?

I'm looking for a laptop that costs around £400, I don't want to stray into the £500 territory but if it's necessary then I guess I have to. I'm not looking to run it at Ultra and I'm satisfied with a Low to Medium graphical setting for the game. I'm also interested in playing WoW and possibly Minecraft on it but I don't see that being a problem due to neither being that graphically demanding.

I don't know much about PC's and PC gaming so please speak as simply as possible, I've typically just inherited old macs from my parents and make do with that.
