I upgraded my Toshiba laptop's processor from an I3-330M to an I5-450M. Before doing so I upgraded the BIOS. After the upgrade my Windows Experience Index went from a 4.6 to a 2.2 Under Device Manager nothing appears to need an update. Everything seems to be working fine. Is there something I forgot to do?
The only thing not mentioned that your processor needs is the graphics driver. Please proceed contacting Toshiba* in order to get the customized driver. The other alternative would be trying the generic version available on our site: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Laptop+graphics+drivers&ProductProduct=Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics&ProdId=3231&LineId=1101&FamilyId=39
