    Motherboard problems?

    Motherboard problems? 10th Jul 18 at 6:52 PM
    I have a self built desktop, that is well used but old. It is now at the stage where either-


    1. The power source works but the screen flashes "no imput signal" on and off as the tower peeps as it keeps trying.

    2. It starts to load, but only gets as far as "Memory Runs at Single Channel" or stops just before that; and then it freezes.


    3. It works.


    Is this a motherboard problem? Can it be sorted? Or is it time to build another PC?

    This can be a power supply issue. Power supplies are under their most intensive load when a machine is switched on.

    If this is a cheap nasty power supply it should probably be binned or promoted to door stop.

    Indeed, and even then its been proved that a cheap nasty 700w unit doesn't always provide anywhere near 700w. In the worst case situation they go pop at two thirds stated capacity, so that means a 700w may only be able to provide 469w.

    There's a 350w Corsair I think it was I installed in my parents computer in 2008. It is still running today, and in its early life that computer was used day in and day out seven days a week. My own 480w decent brand was new in 2008 and is still working today. They weren't cheap, I won't lie, but they are solid and they are SO quiet. The 350w is overkill now for what that computer is used for but my 480w unit is part of my gaming PC. When it does die, it will get a Corsair or an Antec or something like that.

    Have you made any hardware changes to the PC recently? Or installed a new BIOS? Or transported or dropped it?


    Sounds to me like a PSU problem. But worth reseating the RAM and testing it with Memtest:


    https://www.memtest86.com/download.htm


    What sticks of RAM do you have? When the PC does boot, does it detect all of them?


    1. The power source works but the screen flashes "no imput signal" on and off as the tower peeps as it keeps trying.

    The beep code will indicate which component the motherboard considers at fault.

    I'll try the remove and replace; when I get the courage to turn it off again.

    Just the one beep, as it usually does when it boots up. It then flashed "no imput signal" and beeped once again, like it was trying to boot up again. Then put "no imput signal" again and just the one beep as if it is trying to boot up again. It kept trying until I stopped it. That only started today.

    Or it just does the normal one beep as it starts to boot up, but only gets to where I put in my first post, that I numbered 2. That started over the last few days.



    Or it will boot up without a problem. As it eventually did today when I thought it had had it.

    I'm beginning to wonder if it is the 1GB of RAM now that is causing this boot up problem? When I moved to Windows 7 from XP the other year, it struggles if I try to open lots of tabs and I can go away and make a cup of coffee while it is loading them all. It didn't have that problem with XP. It does open them all eventually - apart from the other day, when it went to what I put in the OP as number 2. I then had to reboot and it started without any problem.


    Is it time for me to buy that 4GB of RAM? And it's not the motherboard or PSU?

    Hmmm... 60 is very cheap for a case and PSU. Given how much you use it, it's possible that the PSU has given up.


    As you just have one stick of RAM, it could be that too. As well as trying to re-seat it, maybe try it in a different slot.


    Or maybe take out the RAM, try to boot the PC and compare what happens to what happens when the PC fails to boot with the RAM in. Identical behaviour might mean that the RAM isn't being detected (or is faulty). Different behaviour you haven't seen before suggests that it's something other than the RAM at fault.

    Now that you mention it, it could have been the lots of short beeps. It's only done that a couple of times. If it doesn't start, it has been stopping at 2 in the opening post - but... As said, once it went to that same place (2) when I opened a lot of tabs and it was a struggle to load them all.

    No problem starting at all today.

    Sounds like your bios battery is low and is not retaining the bios settings - if it's the original battery it may be worth trying for the sake of a pound or two

    One thing you can try is leaving the PC off overnight, then booting up, going into the BIOS settings, and checking the time is correct. If not, you'll need to replace the CR2032 battery, and your BIOS settings may have been corrupted.


    If you can't replace the battery immediately, you could try re-saving the existing BIOS settings and rebooting. Or reset the settings to factory defaults, save and reboot.

    Not sure if your PC can boot of usb, but you could burn this below to cd and run through the tests of memory, cpu, motherboard and HDD - try all the tests . It may fail on some test though which could be normal, just take note of the failures
