    i have built a pc and am having a major problem. the first few time it booted it was fine, windows loaded and was working.i turned it off to install the network card but then for an unknown reason it has stopped working. now when it boots up i get no video signal and 3 beeps. the beeps are the same tone and legth and are evenly spaced. the sounds keeps repeating after a few seconds. i read that it could be the memory so i changed it. the beeps have stopped but still no video. it's a brand new video card but slightly used mother board.

    the motherboard is a soltek top mainboard. and the graphics card is a sapphire.

    any help would be greatly appreciated. could it be the motherboard?

    When I built a pc for my daughter using some parts my brother in law gave me, I had 3 beeps on start up. After checking sights on Google by just typing in "error beeps", it did appear to be faulty RAM. Check everything is seated properly and maybe your replacement RAM is faulty aswell. Hope not. Persevere with it. I don't know if you have built a pc before or if this is your first build, but it is a great feeling knowing you did it yourself. Good luck. If you have any more questions I will try my best to help.

    i have reseated every thing and still the 3 beeps.
    this is the first pc i have built.
    i don't really know much about pc's, does the ram have to be blank? i.e not used on a different machine or will any work?

    no, it doesnt matter if the ram was used.. it should work in any machine

    can you get hold of different ram to test with ?

    yes. i have used a ram from another pc from work. its fairly new. 5 weeks old and every thing works on it. i tried it in both slots and the same effect.

    no video 3 beeps.

    i have also tried another graphics card but still no joy.

    i know the hard drive works as i tried it in another machine.

    starting to think its the mainboard.

    any thoughts?

    Looks like a motherboard swap will have to be tried next. It is a process of elimination i'm afraid.:(

    Almost forgot. Could your network card have caused the problem? You did mention the beeps started after installation of network card. Maybe take this out and try again. Sorry for the late reply.

    Did you try the link to the RAM test I gave?

    There's plenty of comment about this being RAM, you need to run a full diagnostic on it. If your 3 continuous beeps is correct it is your RAM. Swapping other parts is premature and could well be a wasted effort since it could still replicate itself in the new setup.

    Since his machine has no video, he'll need to test the RAM in a known 100% working PC.

    Clear the motherboard BIOS settings by moving the battery link. Remove all the hardware, and re-install from scratch.

    if you now have no video and 3 beeps (after it did work), I would say your motherboard has a problem with your graphics card.
    If you've tried a different gfx card and that didn't work, I would say your mobo is damaged.
    It's a bit tricky to test when you only have one set of each thing, but I doubt the memory is the problem because that shouldn't stop the video (gfx)from giving you a signal, which is the actual problem. It's possible the mobo has had a power surge through it.
    You could try and boot up in safe mode and use the onboard gfx and see if that gives you the 3 beeps. If you are using onboard gfx and you are getting the beeps still....Dell are doing some great deals...

    i tried a few things last night. i have disconected every thing except the ram, gfx card and hard drive. still nothing. following some advice from a friend i totaly dismanteled it and started again.

    the system now comprises of.

    a mother board
    hard drive (working)
    cd rom (working)
    ram (brand new and 100% working)
    and (graphics card brand new and working)

    the problems have changed.

    it now beeps once, sounds like its doing something and then shuts down. still no video.

    it is starting to sound more and more likley the motherboard is [email protected]#£%*d
    would anyone agree or am i been a bit rash in assuming this?
