So I've not used my windows laptop for a while now, it had windows 8 on it and I finally reinstalled to the stock windows 7 home premium that worked before.

I've played minecraft on this machine before in the past and its never had a problem, its been able to play most games at really high quality without a hitch.

Specs:
Windows 7 Home Premium 64bit
8GB RAM
2GB ATI Radeon HD 7690M XT Graphics
Intel Core i7 26700QM 2.2GHz

I've installed all the latest drivers, 64bit Java etc. But when I play minecraft, after about 5 minutes it starts to get extremely laggy, then starts to stall and eventually stops and throws up the low memory error. I've never had this before. What gives?

Have you brought up the task manager while playing the game? Sounds like you know how but didn't mention it. It might shed some light on what process is leaking all the memory.

Thats the thing, theres nothing unusual in task manager. Minecraft and Java are the only programs that are installed after I restored the computer. Everything else was running no more than 1% of the CPU, and there was only like 3GB RAM being used while MC was running, I have 8GB. Something up? Nothing was using an un-necessary amount.

Been a while since I've done this but I think you need to increase the amount of memory Java can use. Something along the lines of this:

Alternatively use something like the Technic Launcher which allows you to set the memory limit before loading Minecraft.

You could see if this makes any difference without changing advanced settings: http://www.iobit.com/gamebooster.html

Never tried it but it has good reviews.

low RAM not disk space? you can't get low ram running 8gb unless you have an older version of Firefox that eats ram by the second or someother poweruser VM or super video/photo processing at the same time

That's what I thought but apparently not. I haven't installed anything except minecraft so nothing else is running. Task manager confirms this too. Fault maybe?

Which Java version number exactly do you have installed?

Is that version different exactly than the version you previously ran on 7?
