I am going to have to disagree with the bad rep for the MSI board, I am personally using this MSI Z77A-G43 with an i7 CPU clocked at 4.2ghz.
I have had one problem with it and that was using the corsair ram, now solved when I replaced them with the Gskill Ripjaws.
The component quality on this motherboard looks mid to high range to me certainly not shoddy and with plenty of tolerance for overclocking, I would currently rate them above Asrock.
I think your problem definitely points towards your PSU.
