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.
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.
