How is the 32 bit version of Win8 affecting your PC.
did you download the Win8 software via the windows upgrade advisor?
if so then the upgrade advisor would have looked at the version of windows your were running and given you the upgrade for that version.
for instance if you were running a 32 bit version then you would have got the 32 bit version of win8.
you don't say what the issues you are experiencing are, did you do an upgrade keeping all your programs etc. An upgrade just keeping your files and folders or a clean install keeping nothing.
your CPU is 64 bit but that doesn't mean that you had a 64 bit version of Windows installed.
