Hey guys. I had a problem where my system would only POST exactly once, then never again. I would get a nice beep, a normal BIOS start-up, and I could go in there and do some settings, but when it restarted, I'd just get a black screen (no video) and no beep codes. Successive reboots would produce the same result, even if I didn't change the settings.

To get it to POST again I would have to pop out the battery and reset the bios settings with that jumper! This happened even with a minimally equipped system (just one stick of ram (the regular 1066MHz stuff crucial.com recommends), qx9650 cpu, and NO peripherals (no hard drives, optical, floppy, etc)!

Based on a post I think I read here somewhere, I suspected that each time I went into BIOS and then exited that it was saving some jumbled values and upon the next reboot, could not read its own mess. What I did to fix the problem was explicitly enter all the values for my RAM that the bios detected. It then would save my own values properly and POST on the next bootup (even though it detected them properly!).

I suspect you guys never experienced this problem because you are all HARD CORE and never accept the default ram timings, always putting your own timings in there from the get-go . So you had no idea this motherboard was a problem for regular joes like me.

Anyway, it was this thread that motivated me and gave me ideas to get this problem solved. I am pretty sure someone even mentioned the explicit setting of ram values, but I cannot find that post to credit the individual.

Thanks guys! And I hope my post helps someone.
