I overclocked my t-bird 750 to 1 Ghz on abit kt7 but once yesterday and once today, xp just froze for no apparent reason, i wasn't running any programs except chatting and listening to mp3. then today, when i restarted the system, (don't know if this is related, but) all the emails that msn explorers saves on the computer was gone! what can be causing xp to freeze like that? is it due to overclocking? my temp is ok i think, around mid to high 30s when running a program (i.e. Access). thanks very much!
