Please tell us the model card so we can look for the driver.
If you have 4gb or less RAM you may like the way 32 bit runs better anyway, so you'd be right to Dual Boot long enough to decide. Then we can help you remove the one you don't want.
Everything you need is in Dual Boot Installation - Windows 8 and Windows 7 or Vista - Windows 8 Forums
and Clean Reinstall - Factory OEM Windows 7
