Notice the driver in I5 IS Rejected verses the installed one...
According to that I5 is NOT a better driver for your hardware...
It selected the BEST MATCH for your PC .
The 'best match' is not always the the 'newest'... OR... Newer is not always better .
Testing the theory...
Install the I5 driver manually.
Reboot.
Run SAD.
Reboot.
See if the driver is reverted.
Report.
