Need help installing 2nd Sata Hard drive...

I am in desperate need of some help here. I made a topic a few days ago trying to get help with this problem but the two people who replied couldn't seem to help fix the issue. So here's my problem. I bought my girlfriend a new hard drive a few weeks back because she has been complaining to me about not having enough space for months. So I went and got a 1Tb HDD and just figured it would be an easy install, just like any other HDD, but for some reason her computer refuses to recognize the hard drive in Windows and BIOS. I have tried every thing I can think of. Checked all the cables, checked its getting power, checked the SATA ports on her motherboard, checked the hard drive is actually working, and updated her BIOS, also tried forcing the Hard drive to run at 1.5 instead of 3, although I'm not exactly certain if the jumper on the back did what they were meant too...

So can anyone give me a few suggestions, even if its something Iv tried that has the possibility that it could have been done wrong, as long as u let me know how to do it right.

Now I'll let you know what the hardware is so you might be able to look it up and find any incompatibility issues if there are any.

HDD: SAMSUNG HD103SJ, Website: http://www.newegg.com/Product/Product.aspx?Item=N82E16822152185

Motherboard: GIGABYTE GA-K8VT890-9, Website:http://www.newegg.com/product/product.aspx?Item=N82E16813128288

Oh god, I finally got it working. Turned out the jumpers on the back don't do anything. I had to force the drive to 1.5 with software on my computer. Now I can finally get a break from the constant nagging of my girlfriend. :) Thanks for your help guys.
