    hi all, just lately, my friends pc wouldnt start So i decided to try and fix it for him.. When i push the on off switch, the hard drive led stays on for ever, but no thing happens. the fans turn on and all, but the hdd wont.

    now when i go and disconnect the ide cable, the hdd starts up all of a sudden, the motherboard does that beep thigy at start up and all, but nothing is displayed in the monitor.

    here are the specs:
    WD 80 GB hdd
    Bestec 250W PSU
    512 MB Ram
    K7VTA3 Ver. 6.0 mobo
    TNT2 AGP4x 32MB ram video card
    sempron 2400+ 1.6ghz cpu

    yes i know its old and he is very ignorant and says that his PC is just fine. He wont upgrade

    so like can anyone give me any advice on why this is happening?

    thnx

    sounds like something is dead and my money is on the mobo(cpu a close 2nd), looks like he might need to upgrade after all.

    not a bad rig tho, all things considered, my mate has a p4 1.4ghz(or 1.6) and he thinks its the dogs dangly bits. each to their own hey?

    disconnect all drive cables, remove all cards & ram except videocard & 1 stick of ram. reseat those 2. if have another videocard, try it.

    sorry my bad, need to make sure i read the full post(it might of been late at night here)

    well then that sounds like the psu isnt powerful enough.

    but if it was fine and now all of asuden this i would still go with mobo.

    can you try your psu init first to rule that out?

    hard drive is dead
    guys think, if it posts after you have disconnected the harddrive
    what might be wrong lol
    try a different harddrive
    try a different ide cable
    i'll read it all next time
    and reply when i know what i'm talking about

    didn't want hd connected, just mb, cpu, cpu heatsink fan assembly, 1 stick of ram & a videocard. try clearing the cmos as found it to work sometimes to kickstart a system. try another psu as 5v line on current psu could be dead.

    bad motherboard, ram, cpu or psu can cause it not to show on the monitor besides a bad videocard.

    well, i swapped the psu and ram, but the screen still wont show.

    so how do i know what is wrong?

    should i trust my guts and get a new mobo?

    what is the order of importance?

    1. motherboard
    2. CPU
    3. GPU

    ?

    all 3 plus ram & psu. does the drives seem to be going thru their booting process? try clearing the cmos to see if that does anything.

    well, the drive does seem like if it is acting normal, same sound if i put it on another computer.

    i took the battery off, and replaced that too, but it didnt do anything

    there is no post beep either, when there are no drives connected

    i am leaning over to a dead motherboard
