- unplug your Power Ac from PSU, find jumper clear Cmos .. if you don't find remove battery, let 10minutes .
- pairs of ram in another slot, this is just to make sure whether the slot on the motherboard ram doing well.
- if all the slots are working fine again plug the other ram remember just 1 , it means you run at dual channel ... and sure it is locked securely. reconnect power try turn on system
