Q6700 it is then! Didn't see that there! I hought for a extra few quid I could get a faster processor. As for my hard drive, well, I've got a 160gb at the moment, and I was wondering I could wipe it clean and load Vista Ultimate on it and use it in the pc I'll be building. However it seems to be every day now that my computer switches to a blue screen at random times and says all this stuff I don't understand, shuts down, then when I come to restart it says 'disk read error' or something like that. I've checked for viruses, done what windows told me to do, done everything to try and recover it but it still happens. But if I leave it an hour or so it will boot up fine again with everything still loaded on :/ Is there anything I can get to run a scan and check if my hard drive is ok, otherwise I'll need to get a new one. Or will wiping it clean recover it? This is the reason why I'm going to build a new pc!
