Hello all. I've been a visitor in this forum for some time, but unfortunately what made me register is a problem I'm having. For that, I apologize. I hope this is a good place to put the thread... So, let me try to explain it as well as I can: My computer is having a problem that prevents it from rebooting successfully. Ever since I overclocked my cpu and changed some voltages in the bios to get it stable(vcore, pll,vtt, nb-all within safe values) I can use it as long as I'd like, but if I restart it I get only a black screen. The machine will still be on, the fans are spinning, but nothing shows on screen. I have to turn it off, disconnect the power cable and reset the cmos. Then, I turn it on and it will boot ok. From what I've read in several places this is somewhat usual among those who have the p5q series. I tested almost all the settings inside the bios to find out which one is causing the problem and I am almost sure it is the "fsb termination voltage" option. If I set it to anything other than "auto", I won't be able to restart the pc. I have already reset the bios by removing the motherboard battery and resetting its options, and that didn't work. Am I missing something? Is it possible that a recent bios revision might help correct the problem, since I have a very old version?( mine is 0703, the most recent is 2100 something...) I am a little concerned of touching the bios because something may go wrong, and then it'll be a PITA to RMA it. I've also thought of leaving that particular setting in "auto", but after reading that the whole P5Q series overvolts like crazy, it leaves me a little bit uncomfortable. I really don't wanna fry my Wolfie Check this out for reference. So, I want to overclock it a little bit, but in doing so the "auto" voltages MAY be all over the place. But if I set the values manually, the system gets unstable... Oh, one more thing: I tried mailing Asus Support, and they've been as helpful as a kick in the teeth. Oh well Thanks for the help.
