So tired of crashes

During the alpha builds i had it OC at 1000, same with Openelec and raspbmc, never had a problem then. After the June update all hell broke lose. And besides, the wifi bug that it was not connecting to my router, was happening only with osmc.
About the splash screen, there was a patch released earlier this year: Splash screen is damaged - #6 by DBMandrake
that fixed it back then. The problem started when i put the sd card on my pc and edited the config.txt to force 720p resolution for when the tv is off and the pi reboots, so it gets the proper resolution…after that reverting back the changes doesnt affect the broken splash screen.

What about the fact 1 month ago with the June/July update when the whole system turned read-only after the update ? I was not the only person that had that problem. Did we all have a faulty hardware ?
