Hey, i currently have a Dell Inspiron 531, the Athlon X2 version, and it runs on Vista, however I want to upgrade to 7 just so i have an upgraded home network. My 531 always crashes with constant blue screens, and when i try to run certain software, it says environment error, will Windows 7 fix this, basically I'm asking if it it's worth it to buy it to fix my problem? btw I have already tried to restore it to factory default and i get environment error, and it's not currently connected to the internet, and when i tried to connect it, it doesn't work, maybe Windows 7 will fix that?
