I've built several system over the years, but I've never encountered this problem. I wonder if anyone can tell me what to look for.
I'm building a system with an Asus P8Z77-WS motherboard, i7-3770 CPU, and two 4 GB RAM modules. The motherboard powers up, resets, and powers down, but the system won't start.
The motherboard has diagnostic lights that are supposed to tell me which component is at fault: the CPU, RAM, display, or disk light comes on and stays on, and that fingers the problem component.
But it doesn't work that way. When I power up, the CPU light comes on. It stays on for about 25 seconds, then it goes off, and the RAM light comes on for about one second. Then it's lights-out for a while (a minute or more past power-on, I haven't timed it), and the display adapter light comes on and stays on.
The hard disk light doesn't get into the act... perhaps because I haven't attached a disk yet.
In case it matters, the board was sitting in a box for several years with no battery installed. I put in a fresh battery before I started testing.
Any ideas?
