    hey all,

    My brother gave me a dual xeon motherboard and 2 x 2.8gig cpu's, put the ram in (2 x 266 512ram sticks) and powerd up the system. the motherboard is a intel se7501hg2

    but the fans turn on and off and this just keeps happening, no post screen no error codes. :blink

    im thinking the psu isnt strong enough, its a 430watt psu. I have connected up a cdrom and floppy thinking it checks the connections before a post screen shows, but this doesnt help.

    this is my 1st dual system, the cpu's are matched (so im told)...

    any ideas from some server techs?

    Are you saying it stays on but you cant see anything on the screen or it starts then switches off?

    If it switches of it could be the mobo or PSU if there is power to it but you see anything then I would either say its the mobo or PSU or the CPUs.

    hey bruce,

    sorry im trying to say that the cpu fans turn on and power down, this gets repeated over and over. seems like they dont have the power to keep up when booted.

    The fans could be knackered they do eventually die.

    You could try some new fans if this does not work then probably be the PSU.

    What is the full spec of it.

    If the PSU thats in there is 430W and it needs 450W then thats your answer.

    remember if you need a 450w psu, get a heavier wattage one, as more component you gonna ram into the system, the more "juice" it will take...

    its not in a case at the moment its on my desk, i just bought a 650 watt psu from the store, plugged it in and still the same thing.

    fans start then stop, repeat. still no post.

    maybe the motherboard is knackerd...

    anyone want to buy cheap xeon chips :rolleyes: (joking at this stage)

    its a intel se7501hg2 ,

    im starting to think that the mobo wont boot unless all connectors are plugged in ie. cdrom,hdd,fans,etc maybe it dectects the onboard connectors before booting poperly?

    sebstah,

    Are you using supported CPUs on the motherboard?

    just let the mother stop and start for the last 5-10mins, now im getting error codes

    5 beeps - processor failure

    4 beeps - system timer not opertional

    either the motherboard or the cpu's are not working,

    tried with 1 cpu then both, same error.

    thanks for everyone's help, :respct

    going to stop working on it and search for a new motherboard or find some who can check if the cpu's are fried...

    Sounds like the battery could be knackered along with the cpus.

    Just a thought sebstah but I seem to remember of a similar problem but on a single CPU board. I believe that turned out to be the ram believe it or not, or so I recall - was a while ago. Anyway, as I said, just a thought but maybe U could mess with the ram set up and see if it helps.

    Oh, and as a second thought, I rememebr having another problem that sounded similar which turned out to be a fried CPU:cry:
