  1. hi guys
    i just signed up here in the hope that somebody can help me build my new system because i have tried everything i can possibly think of and now im stuck.
    i decided i liked the sound of the dual core so i got the following expecting to be able to just chuck it alltogether but no such luck.
    i have got the following parts

    motherboard asrock 775v88+
    i heard these are quite good because they take almost any type of ram and in the past i have had trouble with a board not taking high density memory but im not quite sure if they support dual core even though the cpu is on the compatibilty list

    intel dual core pentium d 840 smithfield 3.2 cpu sl88r

    ddr400 1gb ram pc 3200 memory
    im pretty sure this memory is compatible as i use the same memory with the 478 version of the above motherboard with no problems and i used some low density memory just in case and that didnt work either

    maxtor 200gb sata hard drive

    casecom pc case with 350w psu
    i have a feeling this may be where my problem is do i need more power from the psu to run a dual core? i have never done a 775 before but it has always been ok with the pentium 4 478

    when i put all this together everything seems fine the fans go cd rom lights go on but there is no output to the monitor
    please can someone help me im desperate ?

    You failed to mention what video card you're using.
    Sounds more like the problem lies there to me.

    Does the computer beep when you turn it on. If it does then at least you no CPU & motherboard is working. If it doesn't try reseting your bios, it says how in the manual.

    I believe it is ur Case+PSU combo. It probably uses a garbage-quality PSU and that's no good. If it ever fries, it can take out most of ur PC's components. Get a good one from Antec, Aspire, Hipro or Liberty. Or get a case w\o PSU and get a separate PSU from Antec, Thermaltake, OCZ, FSP Fortron, or Enermax.

    Try clearing the bios by moving some jumpers. It will tell you how in the manual of you motherboard.
