    Question GA-N650SLI-DS4 barely reaching POST

    Hi all,

    I'm new to this forum. I see most of you are running much more advanced hardware than I am; but I'm glad I found it, hoping you will help me troubleshoot my issue.

    I've been running a GA-N650SLI-DS4 mobo for many years, and for the past year and a half or so with an E7400 CPU (which replaced the E4500 that came with the mobo). Always worked fine (despite the E7400 not being on the supported CPU list). Also running 4 GB, 4 x 1 GB, DDR2 800 RAM, and the usual suspects of HD, DVD, and video card.

    Anyway, earlier, on monday this week, my PC didn't want to start. Drive lights came on, fans came on, monitor light came on; but that was it. No Gigabyte logo, no post screen, not even the oh so familiar beep. Tried rebooting several times, warm and cold; but the screen remained black and the HD light stayed unlit. Because I didn't have much time I left it alone until that evening; but the same happened (or didn't happen, depening on how you look at it!). I unplugged it, hoping for a miracle.

    It wasn't until Thursday night, yesterday, that I had enough time to spend a few hours on it. I took it apart, and cleaned it. Lots of Texas dust inside... Just for the heck of it I popped the battery out, and left it like that while I was cleaning it. Put everything back together, hooked it up to the AC cord, pushed the power button and ... BEEP! Good to go. Or so I thought...

    The first couple of tries weren't very succesful: it got stuck on the POST screen a few times, rebooted a few times by itself, but after a dozen or so tries I did manage to get Windows to run. I replied to a few week-old emails, then decided it would be wise to make a backup of my files to an external drive, just in case something would happen to the HD. That backup and verify operation took over 5 hours (that's not fast, but normal, considering the hundreds of Gigs); and the PC worked just fine during it. I turned it off for the night.

    This morning I turned it on, and there was the familiar beep. I walked into the kitchen for breakfast, saw Windows load, desktop loaded, after a while the screen saver started and a little later the screen went to sleep. I was so happy! Didn't last long. After breakfast I returned to the PC, wiggled the mouse and... nothing happened. Turned the monitor off and on, only to see "no signal". So I hit the reset button, waited for the beep - nothing. Argh!

    Several reset button presses later I turned it off. Waited. Beep! Windows loaded, desktop looked fine; but as soon as I clicked the first icon Windows locked up. Dang. I walked off again, thinking maybe Windows was creating an error report. Then I heard a beep, had a look, and sure enough: both monitors were black. It restarted behind my back, then locked up before getting to the Gigabyte logo.

    I've been trying to get it to do something, anything, ever since, but no luck. There have been a couple beeps, a few times I got to the POST, but then it either hangs or reboots. I've even seen the gray "select your BIOS settings set or load the last ones that worked" screen; but I've seen it hang on that screen too once, after the timer goes to zero.

    Frustrating. I bought this board years ago because it was one of the last ones to offer a COM port, and firewire, and what not. I have lots of external hardware, and a good replacement that meets my needs is hard to come by, nowadays. So I'd like to revive this puppy!!

    I should have some time on Friday, Saturday and Sunday to test stuff. But frankly: I'm stumped. So if anyone has any suggestions then please fire away!

    Thanks,

    Erik

    Clearly not a man of few words.
    I have an N650SLI-DS4 that still runs, but I use it infrequently.

    We can best help you after you create a detailed hardware list in the PC Specs portion of your forum profile http://forums.tweaktown.com/profile.php?do=editprofile at the bottom of the profile page or in your forum signature http://forums.tweaktown.com/profile....=editsignature.

    Can you test with a different power supply?
    Your current psu might be failing.
    How old is the motherboard battery?

    If you boot to windows, see if there are any unusual hot spots in your system, including your psu.
    It will help if you run HWMonitor or a similar program that reports temperatures and voltages; this might point to a possible problem.

    OK, thanks. I put everything in my profile. The exact drive models are hard to read without removing everything; so I am going by memory there.

    I can; but not until Saturday. It's after midnight here; and I like to do that kinda stuff with a bit of daylight.

    I'm not sure. It's the original battery; that I know. But without having access to my offline email records I can't even tell you how old the mobo is. 4 years, probably. Or even 5. More?

    Whatever its age may be it measures 3.15 V. I believe a brand new one is supposed to measure 3.3 Volts, no? If that's the case then the "old" battery hasn't even drained 10 percent of its capacity. But ... I have some, somewhere; and if I can't find them I'll buy a new one tomorrow and see what that does.

    That being said: I was reading the post about resetting BIOSes earlier. I have done that before; but I was surprised to see that on some mobos it can take several hours to actually to flush the whole darn thing. So, right now, I have everything disassembled, unplugged, and have a jumper on the CMOS clear pins. I'm going to leave it like that until tomorrow (afternoon probably, because of a shopping trip), then put everything back together and see what happens.

    I'll run anything you want me to run, as soon as I can get a stable Windows session going.

    As far as I'm concerned: yes. Don't worry about it too much, though: a long time ago somebody told me "it's not where you put it, but how you use it".

    Thanks! I'll report back tomorrow,

    Buying a cheap power supply is the worst thing your can do.
    My preference is for power supplies make by Seasonic.
    Most Antec, Corsair, Seasonic and XFX psu's are usually highly rated by the top tier web review sites; Jonnyguru, Pcper, HardwareSecrets, HardOCP, and TechPowerUp. There other other excellent power supplies, but they are few and far between. I avoid OCZ and ThermalTake power supplies. There are many name brand power supplies that are mediocre at best. You won't go wrong if you spend a little more and buy a highly rated middle or upper tier psu.

    Did you remove the motherboard battery while you're clearing the CMOS?
    When you boot your system, enter the bios, load optimized bios defaults, save settings and exit, then boot into the bios again.
    You will need to manually re-enter your previous bios settings when you boot your system.
    If you have a saved bios profile of your current bios settings, you can load the saved profile.

    Your motherboard is probably 5 years old.
    HWMonitor and many other programs will display the brand and model name of each connected drive in your system.

    If you still have problems after assembling your system, try booting with only two memory modules in slots 1 and 3.

    Is your cpu or memory overclocked? If yes, what are the settings?

    Unhappy Re: GA-N650SLI-DS4 barely reaching POST

    Hi all, I'm still alive. Can't say the same of my PC...

    Quote Originally Posted by profJim View Post

    Let me apologize for my poor choice of words, when I said "cheap". What I meant with that statement is that buying a good power supply is still cheaper than buying a good motherboard. No, I have absolutely no intention of buying a $20 power supply with a bunch of fake certification stickers on the side, that will blow up every bit of hardware in my case, or a peripheral device! The Thermaltake PSU I have got good ratings back in the day when I assembled this PC; but I'll take your word for it: I'm sure things may have changed, when it comes to quality.

    So I'm a little late, for a few reasons: the good power supply I have in storage (with a whole, working PC attached to it) turns out not to have the seperate 4 pin connector. No need to try that one, then... So I called a good friend who assembled his own system just last year; but he was out of town for an extended July 4th vacation. Perfect timing, bud, lol! Anyway, he was back on the 5th and I picked up his PC, some 30 miles from here. Oh yeah, I love living in the sticks...

    While I was waiting on him to return I did do some experiments, though. I removed every bit of hardware that isn't really needed to run the PC: the 3 PCI cards, the optical drives and the 6 case fans (from way back in the E4500 days). Both HDs are needed to boot into Windows; because even though the big HD is the system drive; the boot partition is located on the smaller drive. Nothing much changed: most of the time the Gigabyte logo didn't even get shown. Other times the machine just hung right after the "verifying DMI pool data". Once or twice I got into Windows, and it would run for hours - letting me do my work! But, the next day, the same problem. Reboot, reset, over and over again.

    By the way: I did get new button cells for the CMOS. 3.3V, as they should be. Doesn't seem to make one bit of difference.

    So on Thursday I got my buddy's PC, took the PSU out, and moved it to my machine. Not an easy thing to do, because of the huge CPU fan in my case. The 4 pin 12V connector is located right underneath the fan, so the mainboard has to come out first. This PSU is a 650 W Antec, should be MORE than enough power. And it's a little more than a year old, powering a system that needs much less amps than mine.

    The results: basically the same. Either a black screen with no beep, or a POST that hangs after the "verifying DMI data" line. On one occasion I managed to boot into Windows, and then I had to scramble to get my work done. Shut it down, and the next day: nothing.

    So the next day I decided to take out some of the RAM. I took out 3 modules, only leaving 1 Gig in slot 1, clearing the CMOS while I did that. I powered on and - BEEP! Ran straight into Windows, and was on for many hours. Thinking I was on to something I restarted, once, twice, fine! I even shut down the PC, and next restarted it. Everything worked is expected! (although a tad slow on 1 Gig of RAM).

    What happened the next day when I got up? Nothing, nada, zilch. No beep, no POST, not a #$#$# thing...

    I took the RAM out and replaced it with 2 sticks (slot 1 and 3) of the RAM that I got after first building the PC. That RAM is identical, but a few years younger. It's been two days now; but I haven't been able to boot into Windows ever since.

    I'm not done experimenting yet, no. One of these days, when I have a few hours to spare, I'm going to take everything out again, including CPU, and start from the bottom up. See if that reveals anything. I think it's safe to say the PSU is good. But I'm not too sure about the CPU and RAM. And the mobo. But at least I still have the E4500 CPU, in case it turns out that the E7400 is a goner...

    Yes, I did. The jumper was in place and the battery removed for several hours, most of the time.

    I've done that a few times, when I had the chance; but it doesn't seem to help.

    That too I've done countless times. After which it should boot, but... no.

    I had two saved profiles: one for the E4500 CPU, and one for the E7400 CPU. I managed to select the latter a few times, but both have now disappeared. Seriously corrupted BIOS???

    Sounds about right, yes. We moved to this place in 2005. Shortly after that I had to buildthis system; because the old one got blown away by the static discharge of a lightning bolt that hit accross the road.

    I downloaded that and installed it on my PC. I have screen shots but can't get to them right now. Voltages with both PSUs appear to be in the expected range.

    As mentioned earlier: did that - no joy. But Monday or Tuesday I'm going to take the whole thing apart (again) and see if I get any error beeps, just running the board by itself. That oughta be interesting...

    Quote Originally Posted by profJim View Post

    It wasn't at the time this problem first happened. When I first got the 7400 CPU I did experiment with overclocking quite a bit; but after a few irritating crashes I decided to keep it at stock settings. And I was happy, cuz the 7400 by itself was much faster than the 4500.

    Thanks for your time, once again,

    At this point, you should remove the motherboard from the case and set it up next to your computer case with the motherboard on top of a cardboard box.
    Do NOT place an anti-static bag under the motherboard.
    • Check that the cpu heatsink and the large roach motel chipset heatsinks are securely mounted.
    • Clean all of the motherboard slots with compressed air.
    • Carefully clean the electrical contacts of the video card and memory models using a new pencil eraser or with a lint free cloth that is lightly dampened with denatured alcohol or 91% pure rubbing alcohol.
    • Check that the 8-pin and 24-pin power sockets are secure and that the contacts are not damaged.
    • Do an overnight cmos clear with the mobo battery removed and with a jumper block on the clear cmos pins.
    • Can you borrow another video card to test with?
    • You can avoid connecting the hard drives if you test with a bootable floppy or optical drive.
    • Try booting with only one memory module installed.
      You might need to try each memory slot, possibly with each of the modules.
    • You can test your memory using Memtest86+ - Advanced Memory Diagnostic Tool installed as a bootable floppy, usb, or optical drive.
      The different download versions are near the middle of the web page.

    Make detailed notes with each boot test including beep codes, and which screens appear.
    You can disable the boot logo in the bios or you can press the TAB key to display boot screen details.
    Pressing F12 while booting will let you choose which device to boot from.

    Thanks for your suggestions. I will get started later tonight, and let the CMOS clear overnight.

    No, I don't have another graphics card, unfortunately.

    Just out of curiosity: I understand the benefits of using a cardboard box; but why not an antistatic bag (like the one the motherboard was packaged in)?

    I really hope it's not more than that. Getting four new sticks of RAM would be pricey; but it would still beat finding a good replacement mobo. And I've tried a second PSU by now; but I wouldn't mind having to buy one of those "80+" things.

    Oh, OK, got ya. I've got plenty of anti-static bags (I'm a bit of a kit builder); but yes, cardboard is more forgiving. I've got it sitting on the box it came in, works great.

    One more message to reply to, and then I'm going to bed. And so is the mobo, battery removed and jumper in place:

    GA-N650SLI-DS4 barely reaching POST-n650sli-ds4-jpg

    I'll be back tomorrow, if I can find enough time.

    Thanks,

    Erik

    Do NOT place an anti-static bag under the motherboard.
    • Check that the cpu heatsink and the large roach motel chipset heatsinks are securely mounted.
    • Clean all of the motherboard slots with compressed air.
    • Carefully clean the electrical contacts of the video card and memory models using a new pencil eraser or with a lint free cloth that is lightly dampened with denatured alcohol or 91% pure rubbing alcohol.
    Did all of that. I used off the shelf rubbing alcohol, with a lens cleaning cloth. CPU and "roach motel" (I just love that expression!) appear to be in good shape. CPU and its heatsink were removed, cleaned up, and a new coat of Artic Silver applied; and then put back. I also located the old E4500 CPU, just in case I want to try it.

    They are secure, and not damaged, as far as I can tell. I'll use my Ohm meter tomorrow to see if everything is still making proper contact. One thing I want to mention is that, on my mobo, half of the 8-pin socket was always blocked by a plastic cover. The manual doens't even mention it; but my 4 pin 12V wire has worked for a good five years now.

    That's what I'm doing right now. It's been like that for over an hour; but I'm not touching it until I get home tomorrow afternoon.

    • You can avoid connecting the hard drives if you test with a bootable floppy or optical drive.
    • Try booting with only one memory module installed.
      You might need to try each memory slot, possibly with each of the modules.
    • You can test your memory using Memtest86+ - Advanced Memory Diagnostic Tool installed as a bootable floppy, usb, or optical drive.
      The different download versions are near the middle of the web page.

    Make detailed notes with each boot test including beep codes, and which screens appear.
    You can disable the boot logo in the bios or you can press the TAB key to display boot screen details.
    Pressing F12 while booting will let you choose which device to boot from.
    No on the video card. Although I might check Walmart.com to see if they still offer any. Would be faster and cheaper (because of their return policy) than to order and experiment with stuff from, say, NewEgg...

    I have downloaded the diskette version of Memtest. I'll run that once I can get to a POST screen.

    I'll make detailed notes, yes.Thanks again for your help!

    Zzzzzzzzzzzzz now,

    Erik
