If you connect them and hard drive indicator light on the front of the case does not come on then you need to swap the 2 connectors around. It's an led which has to be connected the correct way to work. Same goes for the power led on the front of the case.
The motherboard model that you listed doesn't have support for SATA drives. Are you sure that's the correct model? If so, that's your problem, unless you are using a third-party SATA PCI controller. Then I would need to know the model of that to find the driver you are requesting.
I know this doesn't answer your question, but if it helps please rate positively.
To reset BIOS take the battery out, if that does not work you will have to reset jumper J1. In case nothing worked to reset BIOS you can use thrid party software from Hiren's Boot CD to reset the password. You've got Kill CMOS on there, for example which wipes out CMOS. Here's the download link to the entire CD: http://www.hirensbootcd.org/download/Hirens.BootCD.12.0.zip
This is what I would recommend: First, unplug the computer from the power outlet. Then re-plug it and try to start it. If nothing seems to work, but you have power (you can hear the fans start and hear the hard drive spin up, you can open the case and disconnect everything BUT the CPU, memory, and video. See if it starts. It should start up with video and give you an error saying something about no boot device. If this is the case, then start plugging things in starting with the hard drive. If it doesn't work your power supply may be bad. If you have another to swap out, that's good. If you don't, then you really can't check it without a power supply checker. If this doesn't work you are probably looking at a bad motherboard, bad CPU, or bad memory.
