    DELL XPS 410 XPSP2 - system will not boot past the blinking cursor in the corner. I can't get to the BIOS and the PC will not boot from CD. I have tried to hit F1, F2, F8 andF12 at startup to no avail. I replaced the Video card with a known good card, still no luck.
    I tried the unplug/plug method for the I/O panel with no changes.

    The fans are working correctly, so I don't think it was an overheating issue and the power supply is up and running.

    Any suggestions? I'm at a loss.

    thanks!

    No keyboard lights are on.
    The PC doesn't even attempt to load.

    Can you take the HDD out or disconnect it and start the PC and see what happens

    Removed the HDD, rebooted and no blinking cursor.
    Reinserted the HDD, rebooted and no blinking cursor.
    There is nothing at all, its almost as if the PC can't get past the initial PowerOn.

    I removed 3of the 4 memory sticks one by one until only one was left. At which point the PC started buzzing at me. During the removal, I rebooted in between each single memory removal, and all had the same result.
    I inserted the memory back, in full, and rebooted. Still the same nothingness.

    The power supply seems to be on, I can see the fan turning and feel the unit itself humming. Although it could possibly still be bad.
    I unplugged the power supply from the MoBo, which cut power to the system (of course). Reattached and rebooted, nothing.

    Before when it was working did you see the Bios screen for a short time on startup?

    Hi are you hearing any beeps at startup?
    Sounds like a motherboard problem.
    Try..
    Take all of the cards ( RAM / sound / video etc ) off the motherboard.
    leave the CPU.

    Disconnect the data cables to the hard drive and DVD CDROM and hard drive at the motherboard end.

    Disconnect the molex ( power ) cables from the hard drive and DVD CDROM.

    Leave only the 20(4) pin ATX connection from the Power Supply Unit.

    Switch on.
    Do you get any beeps?
