have to reset CMOS to reboot...

[papagiorgio01]

ASUS A8N-SLi Deluxe
AMD 64 X2 4400+
nVidia extreme 7800GTX

I'm able to get to the BIOS, but after I enter my settings and reboot, the screen goes blank. If I power down and reboot, nothing comes up. I have to reset the CMOS in order to get anything to come up on the monitor again, at which point I have to renter the BIOS and the whole circle starts again. I have tried two separate A8N-SLi motherboards. I've also tried two different sets of RAM (one Kingston one Crucial), two different optical drives and even two different motherboard batteries. I am at a serious loss of what to do. I've called ASUS and they suggested it would be the BIOS chip, but using a different motherboard should have solved that, I think.....

Any suggestions?

what are you trying to do?
what do you change in the bios?

Well, I've tried setting the time and date and setting the boot order, just setting the date or making absolutely no changes. I get the same result every time. Even if I don't enter BIOS, it tells me it can't find the boot disk (XP in in the drive) and if I reset from there, I get the same result....

this is all on my "initial" bootup. I haven't even installed XP yet.
