I’m not the biggest tech wizz but my motherboard (msi x370) doesn’t seem to be working, i recently got some corsaie vengence to install and once i did this correctly and turned it back on the motherboard does not light up but the everything else does? Even the usb slots on the back of the motherboard light up but it won’t even load to the bios screen? Any help would be great i’m stuck for idea’s
