What is the make and model of the components in your build?
Please list the make and model of the motherboard, memory modules, video card and power supply unit.
as ko888 said "what is the make and model of the components in your build?"Also just for the sake of it ,check that you'r hardware is seated(reseat it!)and check for any packaging fragments stuck in any slots...(eg).mem,pci-e or even cpu socket
PS. not a bump! i've built many rigs,and this has happend to me.It only takes a super small speck of junk to give you a hard time ...best of luck
