New mobo - comp still won't boot
The computer isn't much better than last time. I'm running an Asus
A7V8X-X mobo. As soon as I flip the power switch on the ATX PS, the whole thing turns on (fans start spinning, etc.), which is bad, because usually the computer waits for me to press the power switch before turning on. I've reseated the mobo, re-checking the metal stand-offs. Those are fine. I've reseated the CPU, heatsink, video card, and memory. Still, nothing at all happens - it doesn't post, and it never sends a signal to the monitor. I know the CPU works, and the RAM and mobo are both new. Any clue as to why this computer won't boot at all? Why it doesn't even recognize the power switch and just goes full-on immediately? Thanks in advance for the help. -- Usenet is a strange reality where you see people beating up a patch of grass where nine years ago there used to be a horse. -Nuke |

After you flip the PSU's switch and it immediately turns on, does the bezel soft-on switch allow turning the system off if held in for 0-4 seconds? Have you tried that yet or do you keep turning it on and off by the PSU switch? Have you tried removing all components non-essential to POST, leaving only the CPU, heatsink fan, one memory module, video card, and soft-on bezel switch? This also means unplugging all other bezel LEDs/reset switch/etc. Also try resetting the CMOS, double-checking all jumpers. Are you sure the power supply is adequate? What make/model/capapcity incl. combined 3V + 5V capacity ? An itemized list of all the systems major components might help if it's possible this is power-supply related. Dave |

Dave I have the EXACTLY same problem with a couple of untested boards I've bought. The test rig I've got works fine with other socket As I've tried, so there's no reason to suspect PSU problems. And in my case, there is no way to turn the machine off other than at the mains (painful!) as there's no PSU switch. BTW when I said 'case' I didn't mean THE case! I test all my stuff outside of cases after I once found a mobo that would only power on when the mobo was not installed inside the case. |

I take it that you've tried the suggestion given in a reply to your previous post of reversing the cable from the power button on the case to the motherboard? As was pointed out, if this is the wrong way round the motherboard thinks that you're holding the power button in continuously - so when you turn the power on at the PSU it comes on immediately, and then, because you've (apparently) been holding the button in for five seconds it goes into the soft-off option, and turns off. For reference, the other common problem from having those cables the wrong way round is the reset cable being reversed - so the computer constantly resets and so (obviously) won't POST. Sometimes a tricky one to diagnose - unless you happen to think of it... |

Have you tried that yet or do you keep turning it on and off by the PSU switch? The switches seem to have no effect whatsoever, no matter which way they're plugged in.

This also means unplugging all other bezel LEDs/reset switch/etc. Also try resetting the CMOS, double-checking all jumpers. I've removed the mobo from the case and tried it that way -- still doesn't work. I was using a minimum of system components too - RAM, CPU, mem, power switch, PS. The only conclusion I could possibly come to is that my mobo is DOA - I'm returning it to the store tomorrow. Are you sure the power supply is adequate? What make/model/capapcity incl. combined 3V + 5V capacity ? An itemized list of all the systems major components might help if it's possible this is power-supply related. I really don't think it's power supply related. I'm running a 450watt ATX power supply which should definitely be sufficient for an ATX-compliant Asus mobo. -- Usenet is a strange reality where you see people beating up a patch of grass where nine years ago there used to be a horse. -Nuke |

Yeah, I've tried reversing the orientation of the power switch - no go. Same for the reset switch. For reference, the other common problem from having those cables the wrong way round is the reset cable being reversed - so the computer constantly resets and so (obviously) won't POST.

I think the mobo is dead ... -- Usenet is a strange reality where you see people beating up a patch of grass where nine years ago there used to be a horse. -Nuke |
