BSOD everytime i 'install something or try and update windows (iastor)

[markswan1]

Okay so i recently rebooted my windows 7 and i have managed to atleast get it running. it allowed me to download mozilla fire fox but not java or any other programs without giving me an iAstor.sys error.
i do not own a windows 7 disc either so i would prefer it if someone could help me get rid of this problem without a disc?
