Disk Boot Error, help please

  1. Okay....

    When my computer has been completely shutdown for at least 15 minutes, upon boot up I will receive the disk boot error. My temp fix is to use the power switch at the back of the tower then quicly switch it back on and boot up again with no problems. Once I do this, I can reboot until my I'm blue in the face and I never see this error again until I shut down for 15 minutes.

    1. I have reformated and re-installed the os (win XP pro SP3)
    2. Ensured the bios boot sequence is correct
    3. Chnaged my CMOS battery
    4. Changed my IDE cable
    5. Ran fixboot, fixmbr and chkdsk /r from the XP cd repair utility
    6. Ran Norton 360 on both my HDD's

    Anyone see something I don't?

    Could also be a faulty power supply. If everything checks out OK with the PS then I would put in a new motherboard.

    It does sound like a Power Supply issue (even though seemingly working)
    I have seen that before and also posted here about it:

    But I've also seen strange issues when the CDRom IDE Cable is faulty
    Best idea there, is just to unplug the CD Data Cable from the Motherboard end and then test for a few days.

    If it works ok, you've found your issue. Faulty CD IDE Cable, or faulty CD\DVD Drive itself :grinthumb
