I've not seen anyone recommend the "old school" method- unplug the power cable and remove the cmos battery for a few minutes, then replace the battery, plug in the power cord and try again. This will reset BIOS if there's no physical damage the MB. (sometimes chips burn out)...

Cheers and Good Luck.

TobiSGD: Yeah, that is why its so problematic. Utilities may not work because system is damaged, or they just dont work because I made something wrong. But, for my defense, I have to say that I did not change any overclocking settings - just turned it into manual. (what should be little bit better). Nevermind, actually, the more that I do, the more I think its physically damaged.

DragonSlayer48DX: I'll try it. But as far as I know, that one should only reset BIOS settings, not BIOS itself. I suppose that BIOS is damaged "in it's core", because I can't hear/see any POST test going on, and also no beeps.
