It isn't in power saver mode, I'm pretty positive your BIOS isn't posting. Meaning there is a problem with some of your settings. Perhaps you need to turn up cpu voltage a little more or check your ram voltage. Most mother boards will keep RAM running at a specified "ratio" with your mother board. If your RAM is running at a 1:1 ratio, that means your rated RAM speed is 666 MHz. So I would either tweak the ram voltage or timings.
EDIT:
If you'd take some time to fill out your system specs in the user CP section, it would be much easier to help ya.
