No power to hard drive with new motherboard

I installed a ECS nForce 570 SLIT-A v5.1 NVIDIA Socket 775 ATX
Motherboard / Audio / PCI Express / S/PDIF / SLI Ready / Gigabit LAN /
USB 2.0 / Serial ATA / RAID motherboard. I got everything connected
but only the CPU and case fan come on when the power is turned on. I
put the original motherboad back in and got everthing to work just
fine.

Is it possible that my hard drives are not compatible. I have 450
watts of power so I do not think that is the problem.

I tried both IDE1 and IDE2 with the hard drives and could not get the
computer to turn on properly. I also noticed my monitor would be on
but was not getting a signal.

Has anyone else had an issue like this?

HMM...

Computer worked with old motherboard

Computer wouldn't work with new motherboard (everything else the
same). Didn't even get a video signal.

Computer worked again when original motherboard put back.

You think there just MIGHT be something wrong with the new motherboard?

While the computer obviously won't load the OS without a hard drive, if
it doesn't send a signal to the monitor with JUST the case, PSU,
motherboard, CPU and video accelerator (or integrated motherboard
graphics) installed there's some problem other than the hard drive(s).
 
I would think that the hard drive would have to kick on in order to
start the BIOS to get the monitor to come on. Is that true?

No.

you should be able to see the bios screen with *no* HD connected...
disconnect the HD and see if the machine posts...if not the board is
bad...or the wrong RAM or some such problem


btw: you may want to try resetting the bios

Hard disk doesn't get involved until after the BIOS splash screen (which
is sometimes JUST a copyright notice) is displayed and the Power On Self
Test (POST) is completed. Some BIOS versions display what drives
(floppy, hard and CD/DVD) are connected but lack of those peripherals
only results in a shorter list. Of coarse with no OS loaded there
usually isn't anything you can do with the computer except change the
CMOS settings. The BIOS usually displays an instruction indicating which
key combination starts the CMOS Setup at some point during the setup.
The CMOS settings often offer the option for the POST to conduct a VERY
basic RAM test, which many people leave disabled to shorten the boot time.

The BIOS splash/copyright notice, POST and CMOS setup use basic video
capabilities that don't require any drivers to be loaded from a hard
drive or other peripheral. Code in the BIOS and the video adapter is
utilized for those functions. A case speaker beep code is used to offer
clues about any problem that interferes with video display during POST.
There are no standards for the beep codes, even those based on a common
BIOS code supplier, as the BIOS code is often customized by the
motherboard manufacturer.
