Just put together new build x58 sabretooth intel i7 990 24gb memory, all working well until I tried to load windows 7 on to new samsung 840 pro ssd, system loaded but then crashed! Tried to use magician on another pc to format but cant as frozen, tried to power off on actual ssd (as suggested in many forums to unfreeze it) but no luck so far - very frustrating. Can load on a WD hdd and it works - tried another brand of ssd and it seemed to corrupt that one as well - any suggestions please?
