Odd... I thought I'd put the clock to 4.4ghz and reinstall windows and its working now. Good job I didnt lose much data. It would seem my mate who was here thought I didnt have a key, so he used a 'loader' which then had to reset the computer, after that it wouldnt work at all. But I've now activated my windows with a legit key, running well. Although my ram is at 1333mhz instead of 1600mhz, but I'm scared to change it
