Hey guys, i bought the msi z97s sli krait board a few days ago and i just bought the i7 4790k and 8gb of hyper x white ram, and my ram arrive today and i put everything together, and it told me something about." motherboard or memory has changed" so i selected go to bios and i went to the bios and changed the date and time, then looked at my boot priority,(everything looked normal) and hit save and exiy. But now it goes to a black screen and has like an "s" in the coner and then "A2" and just sits there. Ill press a button and it'll restart the cycle then go to the A2 screen. Any ideas how to fix it?
