Hi guys, ever since updating to 10.7.3 Lion has been acting very weird... Crashes after waking up (I'll click to open an App and the icon will bounce indefinitely and the app won't open; CPU peaks for no apparent reason; amongst others).

My internet connection here in London is on the slow side and it would take me a good 6h to re-install it through the recovery HD. I have, however, a recovery USB with the installation files for 10.7.0 but I was wondering if re-installing 10.7.0. "on top" of my .3 installation and then using a Combo update would bring me any sort of conflict.

Any advice? I wanted to avoid swiping my HDD, clean installing and then using the migration assistant to recover my stuff from TM... that would take as long as using the Recovery HD to re-download a copy of 10.7.3.

Thanks!
