I've rebuilt my PC, got a hold of a version of Vista64 and got it all up and running. I've also installed my new copy of office so my email is working fully again, which brings me to another point. If anyones been trying to get in touch and I haven't responded then feel free to ping me again as email should be back to normal.
I now have to reinstall all my normal software again, which will take a couple of evenings I guess, but I hope that by the weekend, I'll be back to normal - but with my fancy new quad core. I have also gotten two new terrabyte drives to try and get rid of all the little drives my PC was using, so with any luck... I shouldn't have to do this again for a long time!
