Msi board i7 cpu and windows 7 issues

Hello,


i just upgraded my mother board and cpu plus ram i got an msiz77a-g45 with an i7 3770k unlocked and kingston hyper x ddr3 1600 ram i installed a genuine copy of windows 7 professional and finished all the updates and after two days it suddenly shuts down and the hard drive doesn't read ( it's basically a soft brick) causing me to reinstall and try again i've just updated the bios on the motherboard but has any one else had this type of issue?
