    I have a dual boot sytem with Windows 7 64 bit on one drive and XP on another drive.

    Everything was working fine until yesterday.

    I clicked on the shutdown button on Windows 7 and everyhting went blank.

    When I rebooted nothing happens and the hard drive light just stays on.

    When I boot, the drive comes on and the system starts but then it shuts off and after about a second or two it re-starts but doesn't boot and the HDD light just stays on.
    The monitor doesn't come on so I replaced the video card thinking it was that but that didn't work.

    I can't boot from a image cd or from the windows 7 cd but the CD drive runs but nothing happens.



    I'm at a loss to figure what's wrong.

    Any suggestions?

    How old is the PC? This might be a hardware failure of some sort. Since you can't boot from the Win 7 DVD, this would indicate that the problem is not software. I would first check that everything is cleaned out, dust etc., then check that all connections are good by reseating all connectors. (turn off , then unplug the power connector first, then ground yourself to the PC frame) Pull all connectors one at a time then reseat them. Plug the power back in and try to power on and boot while leaving the cover off (for some reason I think this is a Desktop, if not a trip to a professional may be needed) If you still have the problem, then a trip to the aforementioned professional may be needed. (I have no idea how PC literate you are with hardware problems)

    I built the pc some time ago and replaced the motherboard a couple of years ago. It's an ASUS P5Q SE/R
    I also suspect the monitor but not sure if it would give the symptons I described.

    I did pull and re-seat memory etc.
    I'm wondering if the BIOS took a dump.

    Or maybe the motherboard went bad.

    In other words, I have no idea at this point what to do.

    Thanks for the suggestions.

    Do you have another monitor, or know someone with a monitor to borrow to plug in to see if it works? This would elliminate the monitor as the cause.

    Usually if it's Mobo/memory it beeps error codes. If you hear no beeps then I suspect monitor.
    Mine booted to windows I logged in and it went black. I rebooted and it started bios and then went black. No beeps, nothing

    Edit: Meant to say if you are hearing beeps from board then depends on your system what they mean. Have to look it up on motherboard site

    It seems to me it must be something with video. If you do not see the bios POST screen at all but the drive spins up, it would seem that the unit is actually posting and booting but you do not get a display of what is happening.

    Could also be a bad power supply. Disconnect everything except the video card and one stick of memory. See if you can get into the BIOS. If not, and there are no beep codes, it is probably a bad power supply or a bad motherboard. If you can get into bios, put things back one at a time until you find the culprit.

    Banyarola,
    Hello... You might try if you have access to a newer type TV, swap out your monitor and run your PC into it, if you have the inputs on the TV.
    I run my OS's to the TV sometimes and enjoy the large monitor. Regards Fred

    Well guys, thanks for all your suggestions but I did a google and found the problem.

    I unplugged the PC and removed the BIOS battery and re-installed it and then the system booted and I reset the boot drive sequence in the BIOS and all is back to normal..

    I just got it working this morning and haven't re-booted yet but it should be fine. At least I know what to do if it happens again.

    It's beyond me why the BIOS got corrupted.
    I guess stuff just happens.

    Thanks again for all the suggestions.
