I have been building computers since 1994 and I'm familiar with the setups and what not. I have also followed the manuals and double checked everything so that I didn't miss anything. Tower powers up, mother board is powered up, but my monitor doesn't turn on at all. It stays in sleep mode. Any ideas what it might be or what my sleepy eyes might have missed last night?
