The problem is that my friend cant run windows 7 on his processor : whenever the OS starts to load, screen freezes for a sec and the PC restarts (tried 32bit and 64bit).. tried to start it with a 20 % oc (2.3gh) but still wont start.. He will be buying an e6700 tomorrow but im wondering could the problem be cuz of something else.. He has an ati 3670 512mb video and 2gb ram and an asus MB so i dont think that it would be cuz of any of that.. All of this is cuz ive seen 3.5ghz OCs on the e2180 and i think it might be better just to get a good cooling and OC it.
