I just bought a ECS L4S8A2 SiS 648 Motherboard for my lil cousin the other day. I hooked up everything but when it i start it up it locks up at the beginning. I tried booting it from the cd-rom to install windows but it still doesn't work. I can get into th bio setting sometimes and it freezes it up in there. Any suggestion out there on what the problem is? Please help.
