well..... i saw on another forum that some people had the same problem. it seemed that when they changed the setting in the bios from sata to ahci it fixed it. so sceptically i just did a re-install after i changed the setting... and its fixed all the problems i had (see my earlier post). as a experiment i changed the settings back and i had all the same issues. so at the moment 7057x64 is running smooth
yeah I know a lot of companies that were on the "we will not develop for x64" bandwagon, but changed their tune after a long enough stride.
