I've given it another go.
I did some Googling and found a tutorial, I typed some commands into bash and there were loads of errors but it's seemed to have worked. I think it might be fucked though, everytime it boots memtest pops up, and goes through many loops, and doesn't generate any errors. I left it running for 2 and a half hours and it just kept looping round, when I pressed ESC to quit and reboot it just locked up.The first time I saw memtest Ithought it was a bios thing as it looked like my BIOS setup, however I soon discovered this wasn't the case as I could still access the boot menu and BIOS set up. I've bypassed it and booted into Ubuntu and it seems to be running alright, the version info screen says version 6.06 so I'm not too bothered at the moment, if anything else fucks up I'll tell you lot.
