I just built this PC with a Foxconn G31MV-K mobo; Intel E5200 Dual Core 2.5 Ghz CPU; Kingston 2x1Gb 800Mhz RAM and a Vorsichti 430W PSU which are brand new. It booted but I can not get the keyboard to respond. There are no light/s but it flickered when I booted it. I need help, I'm a beginner and thank you.
