I did two things different recently.

First, I changed my RAID 0 from the Marvell 9128 to ICH10R.

Second, I flashed my BIOS from FA to FE.

My motherboard is a Gigabyte GA-X58A-UD5.

During the bootup screen, sometimes it freezes and I would have to do a control-alt-delete.

Any idea and what if I reflash back to an earlier version of the BIOS? Does the freeze harm the system?

Thank You
