    The problem begin with a crash, no BSOD, no error

    messages. On trying to restart the PC would power up

    momentarily, shutdown, then try to powerup again

    repeating this process. This sounds like an issue with

    my BIOS settings. I reset the motherboard by unplugging

    the power, turning the power switch to off, moving

    jumper to the reset position, removing the battery etc.

    Try to start the PC. Same thing happens. Now I think it

    may be my graphics card. At the time there was a radeon

    HIS HD6950 in the PC. I replace the card with a nvidia

    GeForce 550GTX TI. The PC starts & post.

    All is fine for maybe an hour. The pc once again

    crashes with no errors. This time when restarted it

    powers on for maybe 4-5 seconds longer than it did with

    the HD6950, but will restart, power up & stay powered

    up without posting.

    The only way to get it to post again is to reset the

    motherboard as I did above. At this point I was leaning

    more towards my power supply possibly becoming weak.

    Until I started to notice the USB ports on my

    motherboard would stop working not long before, or

    immediately after not working again until i reset the

    motherboard.

    And I can’t update my BIOS because AsusUpdate never

    works & I’m not sure how to do it with the .rom and dos

    so I’m not too comfortable with it.

    Thanks for any advice, need to know if my next move

    should be to try swapping the PSU or swapping to a new

    mobo, thanks !
