I have a problem on DH67BL board and CoreI3 processor, Win7.
IPhone doesn't syncronize with PC using Itunes, it hangs up on
stage 2 data backup. Same Iphone on other computres and my notebook
syncronizes perfectly. Latest drivers, updates, itunes installed.
My suspicion - it is some sofware problem - chipset drivers or
their incompatibility with ITunes
my 2 cents:
- see if chkdsk helps. Maybe some backup file used by itunes has issues.
- try a different usb port to sync your iphone
- switch to icloud for the backup of your iphone
- reset the bios settings to default. Which BIOS version does you have DH67BL has? You can check the download section if a newer BIOS exists (the readme of every BIOS revision lists the issues resolved). From my personal experience I would be careful with a BIOS update as it sometimes introduces new problems and not all versions can be downgraded.
