Hi Glenn
R you OC? What time of day is this occuring? What kind of PS do u have? R u using a UPS? If u r OC does changing to default settings change anything? My first guess is that you have a low power or other power related problem. The first thing I would do is to get a DVM and check your output power at boot. If u need a new PS that is the inexpensive option. However, I think your best bet is to go get a UPS that has a power boost. This is so that when the utility voltage drops it will automatically boost your voltage to what the computer needs. Computers do not like brown-outs! The worst times of the year for power fluctuations are from Thansgiving day to about the 10th of January when all the Christmas lights get turned on in town (about 5pm till about 10pm) and from about June to September when everybody starts kicking on their AC. If this is the problem my recommendation is for an APC ups (www.apc.com). I use in my household a Smart-UPS 1000 on my main computer and a Smart-UPS 700NET on my kitchen computer. Both of these UPS's allow you to monitor the utility power in real time and if you want to get fancy they will also make an unattended shut down of your system while you are away if the utility power cuts out. ********** Clear Skies, Janice |

P/S is Antec 430W - should be more than enough. If it was a power supply, I would think it would happen anytime of day. Plus, it nearly always works on a Reset. As it happens I generally boot about 8-9:00am local, and don't have problems late in day when other "brownout" conditions might occur, i.e. peak evening hours. No UPS, just Surge-protector (Curtis). Haven't added any additional components lately that might trigger this problem. But have the following installed/attached: 2 internal HDD 1 internal FDD 1 internal USB 7-in-1 card reader 1/2 doz. external USB devices (printers, scanners, cradles, etc.) 3 CD/DVD drives 3 case fans (80mm), 1 CPU fan. I had previously checked power requirements (not related to this problem) on a web-site that had estimates (sorry, can't remember where), and I seemed to have more than enough power, even for boot (initial surge). 2 PCI cards 1 AGP card - Glen Ottawa (Remove the ".NIT.invalid" from the end of my address) |

If it really was a power problem, you would expect the computer to crash sometime during when the funny noises are at their peak. The audio usually uses a linear regulator to get clean power, so even if there were fluctuations in the power, the audio should be the last to know about it. A source of sounds like that, could be a problem with any amplifying device in the sound path. An overloaded operational amplifier for example, may oscillate (so-called "put-put" sound). I assume you are using amplified speakers, and not connecting passive (unpowered) speakers to the computer. If I had to choose a device to remove first, from the list above, it would be the USB 7-in-1 card reader. Just a guess. HTH, Paul |

Next time this happens I will take your suggestion and remove 7-in-1 reader. But, as this is an intermittent problem, might be some days before I can establish it fixed or not. I had already removed the cover, and tried to make sure all connectors were secure. Removing/reinserting cards, cables is next. Ta, again Glen - |

Just a guess. > >HTH, > Paul Hi Paul, Don't know if you are monitoring this far back, but thanks for the pointers. For anybody else with a similar issue I ended up removing devices one at a time until everything external or internal (except for enough to boot a working system) was removed. Every time I unplugged or removed an item, the problem seemed to go away for a couple of boots, but it was just "messing with my mind, man". 1. Internal 7-in-1 USB card reader - no change 2. Firewire connector - no change 3. Dlink USB FM-Radio (always a suspect) - no change 4. 2nd Maxtor SATA HDD (always noisier than the other Identical drive) - no change 5. CD-RW drive (always "hunted" more than the others) - no change remaining CD-R and DVD-RW - no change 6. In a fit of frustration - unplugged ALL external USB gear, printer, scanner, cradles, etc. including unplugging from Surge Bar in case a "brick" was producing electrical noise - no change. 7. Powered off AltecLansing speakers (but not disconnected) - this seemed to help but not definite 8. Unplugged RJ11 connectors on PCI modem (old USB). This also seemed to help, don't know why, but I have left unplugged for now. Was convinced this was the problem device at this point, so powered up the speakers again, but I am now back to 9. The Altecs. If I just power off from the small desktop wired remote, I still have the problem. I have had to unplug the Audio-Out from the motherboard completely. OK for most stuff, but Doom lacks a certain appeal with no audio. Things improved a bit, when I unplugged the Centre channel connector, and kept just Front L/R, but now all audio is unplugged. So I have to find some spare, powered speakers, and see if it is the speaker amp, or the onboard audio on Asus m/b in order to finish the troubleshooting. Paul, do you have a feeling one way or the other - speaker (amp) on m/b. If it is m/b, easiest would be to add PCI Soundblaster card?? If nothing else, I cleaned up some of the clutter under my desk, got a new, better surge-bar, and somewhere along the line almost doubled my DSL throughput (probably bad RJ11 from wall to DSL modem). - Glen Ottawa (Remove the ".NIT.invalid" from the end of my address) |

Perhaps you could plug into Lineout and listen to the output that way. Many AC97 audio solutions can drive a 32 ohm load on Lineout, but are weaker on any other outputs (rear L/R, or center/LFE). A 32 ohm set of headphones should work on Lineout at least. The other outputs will be very weak by comparison. Since your fault isolation has pretty well reduced you to mobo or powered speakers, I'll have to go with the powered speakers being at fault. I've noticed some brands of powered speakers, use a goofy connector scheme to connect the components together (i.e. 5.1 computer speakers), and if there is any fault in that connector, strange things can happen (like speakers go to full volume on you). If you have a multicontact connector somewhere on the Altec, inspect it and see what shape it is in. Look for corrosion or discoloration, as that may put enough ohms in the path to cause instability. Motherboard audio faults include: 1) Completely dead output on one or more of six output signals. 2) Sound volume reduction or distortion after gaming for an hour (cause unknown). 3) Sound issues that seem to be game related (like a driver issue). 4) At one time, certain brands of AC'97 sound chips had quality control problems. This would give (1) at first power up of system (infant mortality). 5) Static sound, caused by underrun/overrun of sound data, and related either to bus latency or IRQ problem. Typical fix, decrease PCI Latency setting, enable Delayed Transction setting in BIOS, or put Soundblaster card on slot with an unshared IRQ. I've not heard of a motherboard fault causing a "put-put" fault, as there really aren't any amplifiers of note in the motherboard audio path. There is the headphone amp, which boosts the output enough to drive 32 ohm headphones, but I've never heard of a specific problem caused by that. Paul |

Have been fighting a no cold boot problem with A7N8X for 18 months.
Whenever cold, it wouldn't start, e.g. only hard drives spinning and fans running. However, if I let it warm up, it would boot and run fine thereafter. After lots of dithering, reseating memory and video board, etc., I bit the bullet and decided to start major surgery with a new power supply. Eureka. Success the first time. No more problems as far as I can figure out. Tom Glen McLean wrote: > Hi folks, > > Getting a strange boot problem over the last week or so.

Tom,
I was suspecting a similar issue with mine as well. For a few times what I did was turn on, and leave at the PowerOnPassword, and let it warm-up while I went for coffee. Seemed to work a couple of times, but I think it might have been another red-herring. See my response to Paul above for additional possibilities............

I have decided it is not related to my speakers, or an audio issue as such. Because results of troubleshooting were so hit&miss what with all the cable moving, unplugging, replugging, etc, I think I was chasing the wrong thing. The noise is present whenever I have cables plugged into my Adaptec 5100 PCI 5-port USB card. The problem is aggravated by having a mini-USB cable plugged in, but with no device on it, i.e. not terminated. (It is for a Harmony Remote control that can be updated/configured via web site). But there is some additional noise no matter what is plugged into it. I have had this card since the first days of USB2.0, and it has gone into 2-3 different PCs over the years, so maybe it is self-destructing. The 4 USBs on the m/b are not causing the same (noise) symptoms. Nor does the internal 7-in-1 card reader attached to USB56 headers on m/b. If I unplug everything from the Adaptec card, all is dead quiet (sound-wise) on boot. I will try relocating the Adaptec, maybe right down to bottom of case, last slot. I did replace all my case-fans awhile ago with quieter models that sense heat and slow themselves down (Q-fan does not work on my Rev.1 board). Cannot say if problem started then or not. I did not consider that noise via USB could work its way through the chain this way and cause those symptoms, another red-herring perhaps? I don't want to buy a new Adaptec (or other) card until I have sorted out the cause for sure. I could try a hub, which would isolate cables, etc from the electrical noise of the system, but figured performance would suffer (Zip750, external HDD, etc.). So now I need a new excuse to replace my speakers with better sounding ones ;>) Appreciate your help............................. - Glen Ottawa (Remove the ".NIT.invalid" from the end of my address) |
