    Ive recently built a new PC *mostly with used parts* such as the ram,motherboard,gfx card,HDD,DVD drive only thing that's new in the PC itself is the PSU anyways

    so after getting stuff screwed in and finally getting it to turn on i get nothing on my screen, the screen isn't dead (far as i can tell)its on standby mode (orange light but black screen) plus a picture comes up when its not connected to the PC saying no signal also its an LCD screen, i know the Mobo works as i saw a video of it (won it off ebay) Ive tried two different AGP GFX cards 2 different brands of ram even taking them both out and i don't get any beeps which im pretty sure its meant to? its got an on board VGA port so i also tried that when it didn't pick up anything off the graphics card all the fans and lights work/are on

    Ive replaced the CMOS Battery with a brand new one Ive tried resetting the BIOS also (maybe i haven't set it up right) but the only way i can turn it off is by the PSU if i hold down the power button it doesn't turn off and there is so reset button so therefor there's no rest sw connected on the motherboard (as it doesn't exist) heres some of the specs

    Antec EarthWatts 430W PSU
    Pentium 4 2.4GHz Socket 478
    MSI MS-6533 Motherboard
    512MB ram
    ATI Radeon 850X AGP gfx card

    Ive googled and found out about the resetting the bios thing as i also saw it in the manual i think im running out of options im very sure its just something i haven't plugged in ive made sure everything's plugged in over and over

    only thing i can think of is im not using the ram that came with the motherboard (at the moment) plus it came with another stick of 256MB which i haven't used the 2 together in the video it has both being used and working on an LCD screen ive the video i notice the only thing he has plugged in is the ram,processor and the LCD screen plugged into the mobo VGA port ive also tried another LCD screen that i with my main PC so i know it works...

    Any ideas? please reply as im thinking theres nothing else i can do but hoping there is
    thanks in advance

    disconnect all data & power cables to drives. reseat the ram. remove the agp card so can use onboard video. try another psu just for testing. try the motherboard out of the case as maybe there is a grounding problem. make certain cmos jumper is in correct position of normal not clear cmos.

    I think you probably already know what I'm going to say about that!

    You will only get beeps if there is a beep speaker connected to the motherboard [not regular speakers through the audio jack!]
    If such a speaker is present and connected it usually indicates the CPU isn't powered.
    Have you definitely got all the plugs connected and correctly?


    Check the following:
    20-pin ATX connector
    6-pin AUX connector [your PSU does not come with this connector, you are presumably using an adapter for it?]
    Molex connector for graphics card
    Molex connector(s) for hard disks and CD/DVD drives

    All of these connectors are required for your system to boot, as unlike SATA, IDE drives must be powered if they are connected to the board, else they will hang the system.

    The 6-pin AUX connector is a relic of just how old that motherboard is, it's not used on power supplies any more as it was replaced with the newer 4-pin ATX+12V connector around 7-8 years ago. [Not directly, the 4-pin carries 12V, the AUX carries 3.3/5V, but this reflects the changing layout of boards]

    The 6-pin AUX connector looks like this:

    ah at the moment i dont have the speakers connected up i think it might because whatever i have i dont have plugged in (as in the 6-pin AUX connector) as this is my 1st attempt to build a PC and the only reason im 90% sure it does work as the floppy port *near IDE 1 and 2* has bits of it broken (but im not using a floppy so its not really bothering me) the video shows the same part in the condition it is in but yeah

    ill have to try have a look around as you might know it fits in one of them tiny cases...its very painful to have big hands for this thing i wish id know how small the motherboard was haha, yes just looked at the manual and i have nothing plugged in there haha sorry feel a bit stupid now i read the manual wrong and thought it had something to do with the modem (or a part near it is)

    ah yep was looking at the wrong diagram um what would be needed to get this connection seeing my PSU doesnt have it just something it does have? (such a moltex to 6 pin AUX?) if such a thing exists? or would it be easier to find a converter/adapter for it? or will a new PSU be needed?

    The things i know that i have connected are...

    HDD,DVD Drive,Power to the motherboard,Power to the CPU and the Power SW

    Kylebacon, next time edit your previous post instead of double posting as per forum rules. how many connectors from psu to motherboard are plugged in, 1, 2 or 3?

    Rule of thumb is.
    You assemble the PS, MB, CPU, and on board video out of the case on top of a non-conductive bag. Wear a grounding strap while touching/installing static sensitive components.

    First make sure the basics work before adding more components.

    It could be your RAM, Video card or power supply and or connectors or a shorted MB. Decent MB have good short protection circuitry.

    Go one step at a time.

    Good luck

    reseat those 2 to make certain are seated properly. did you check the cmos jumper was in correct position? did you remove the data & power cables to the drives? are you using onboard video not agp videocard? have you tried another psu? have you tried motherboard out of case? any domed or leaking capacitors on motherboard?

    the way things are going i will end up doing it all over again trying it out of the case and perhaps another PSU ive tried both onboard and AGP VGA ports there was no jumper on the cmos bit (as in you get to choose to keep the data or clear it?) so ive put one on (may of taken it out now) on the keep data pins its got a new CMOS battery in there which has never been used till trying to get this to work when i turn it on it makes sounds not beeps but like its loading sort of sound (think its the DVD drive)and no theres no leakage or anything of that kind

    leave the cmos jumper on pins 1 & 2 according to manual page 2-21.

    don't worry about the 6pin connector. i think you now have a DOA(DeadOnArrival) so return it for replacement or refund.

    Why the battery replacement?
    It's only to store volitale BIOS info when powering down.

    One more question.. Did you remove the AGP video card before trying the on board video?
    If not, remove it.

    I was just trying everything possible in hopes something would get it running and yes i did try with no card installed in sigh wish it didnt die i didnt do it on carpet nor did i give anything a shock but there is one thing that bugs me a little on the video..he doesnt have anything connected to the motherboard (as in the HDD LED Power SW etc) yet its working so unless how they had it setup was just out of sight it seemed a little odd (they had the other plugs plugged in though)

    if anyone's interested in the video

    http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=180588361951&ssPageName=STRK:MEWNX:IT

    scroll down a bit and click video im not able to pause it either to get a better look id send it back but meh id only get $12 the postage was $14.90 which seems a bit over priced but ah well was happy when the motherboard got here also took a week to get here

    can use a slot screw driver in place of power button for test purposes. that is ddr ram not ddr2 ram.
