The blue screen is due to hardware problems, or any software (could be drives) that is stopping a hardware form functioning properly.
Try giving ur PC to some another technician or pc geek and ask him to find/fix the problem.
If HP is really offering you a I5, so they get to keep your i7 and do the adjustment themselves fix and keep your i7 and you end up with a i5.
If it is software problem, try formatting your pc and make sure you install the correct driver files this time.
i.e compatible with the OS and make sure it is updated.
The clock speed is slightly faster on the I5 but not as good anywhere else it would seem.
