Computer intermittently won't boot, no beep

  1. Hi,

    My computer won't start up. When I press the power button the lights all come on, the Hard Drives spin up the CPU fan starts spinning but the computer won't do its beep and nothing will come up on screen.

    I can sometimes get it to work by trying over and over and over it will sometimes eventually beep.

    This may take one attempt or dozens with no sucess.

    I seem to have the greatest sucess at night time when it will usually start after no more than 5 attempts.

    Once it is on there it has no problems, I can restart it as well (e.g. from the bios- save and restart)

    I thought it was the powersuply so I replaced that, I think it might have started working better but I might be just crazy.

    I don't get any beeps when I remove all the hard drives, the Video card, and the RAM

    Or if I remove any one or two of these things, still no beep

    I've tried reseating everything including all cables

    I've taken out the CMOS battery and then put it back in.

    This is what I'm using:

    Antec TX1050B File Server Case
    Antec ATX TruePower 650W
    Asus P5B-Deluxe-WIFI 775, CORE2EE, P965, 1066FSB, PCIEI6, AUDIO, GbLAN
    Intel ATX E6600 CORE 2 DUO /2.4GHz/4MB CACHE/1066FSB/LGA775
    Zalman CNPS7700-Cu Cooler
    Kingston DDR2 4096MB(4x1G)PC6400 800Mhz
    Gecube Radeon X1950XTX 512MB Dual DVI GDDR4
    Maxtor DiamondMax 320G SATAII (16MB cache)
    Western Digital 500G SATAII 7200 rpm HDD(16Mb Cache)
    Samsung 750G 7200RPM 32MB Cache SATA II

    Thank you very very mcuh to anyone who can helpTV

    Next time you try to boot up and it fails insert the windows OS disc and then reboot and see if it will boot from that without any problems. If it does then run the manufacturer's diagnostics on the hard drive as it may be failing.

    I don't have a CD rom drive, I'll try booting from a flash drive or something.

    I can't even get into the BIOS though when it's having it's problems though

    No CD drive, how did you install Windows and all your software?

    CD drives are very cheap these days and come in handy especially under these circumstances.

    Alternatively you could take the hard drive out and hook it up to another PC with a USB adapter and run the diagnostics from Windows.
