D530s will not power up, odd blinking green LED on mobo

I have been all through HP docs and no info to be found. My D530s shut off unexpectedly when I unplugged a USB device. It will not turn back on, when I press and hold the power button the power LED blinks green constantly at a medium-fast rate and continues to do so until I let go of the power button. No system activity or power on occurrs. If I look at the mainboard, the green LED by the CMOS battery is blinking constantly at a medium-fast pace (no sequences, it is constant blinking at same rate). If I unplug power it keeps blinking green until the caps drain out. When I plug in power it starts blinking again. What do I need to replace, anyone know? HP's site has no info on this and i've been through all of the tech docs. thanks in advance-

Ok, this is acting as if your MB is getting power but doing nothing with it. This very well could be a MB problem where something (unknown without looking at it) is fried. Just for grins, take the cmos battery out and let the pc sit for 1/2 to 1 hr before putting it back. If this does not work, I would contact HP for a replacement MB.

Please make sure all devices are connected to your computer properly. Access it in safe mode and I am sure it would run, in in the safe mode just clean Windows registry database using some reliable software such as Reginout Cleaner. After cleanup process, start your computer normally.

Hope it would help you.

2. Click "Start", type "APPWIZ.CPL" (without quotation marks) and press the "Enter" key.
3. Highlight any software or program related to the scanner and click "Change/Remove" to remove the driver.
4. Click "Start", type "DEVMGMT.MSC" (without quotation marks) and press the Enter key.


The operation requires administrative privileges, please click "Continue" when the User Account Control dialog-box appears.

5. Click "View" and select "Show hidden devices".
6. Click the "+" next to “Imaging Devices”. This will show all Imaging Devices previously and currently connected to the computer.
7. Right-click on the Scanner Band scanner name and left-click on “Uninstall”. If the scanner is listed more than one time, uninstall all occurrences of the scanner.
8. If you see “Other Devices” in the device manager list, click on the “+” to view the list of Other Devices.
9. Right-click on the other device and left-click on “Uninstall” from the list. The scanner may be listed as any of the following:
