Plugging in a new GPU denies my PC of boot

Hey guys, I scoured the internet for answers. No answer solved my problem, but I saw this is a common issue for installing new cards. So, the problem is as follows:

I own this computer- http://www.newegg.com/Product/Product.aspx?Item=N82E16883107391 and have for a while. I got new computers and gear, so I gave this one to my little brother. He wants to play MineCraft on it but the onboard graphics kind of suck. So, I bought this- http://www.newegg.com/Product/Product.aspx?Item=N82E16814150655&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_- for him.

On the installation of the card everything seemed swell. However, as soon as the computer was powered on I found that the computer would no longer boot. I changed the VGA back to the onboard, but the screen was still black. If I take out the card everything is dandy again, but after I plug it in again, no avail.

I tried wiping old drivers, installing new ones, changing the graphics priority in BIOS, just having one stick of RAM, and moving the card around in the slot. Still nothing. I consider myself good with computers but I'm stumped. The only thing I can think of is that the card or slot is bad, or that the PCs PCI express slot is not compatible with PCI express x16. Any ideas?

I really don't want to have to return it, and I don't want to buy another one. Any response helps. Thanks.
 
Solution
the pci ex slot is backwards compatible. should be fine. what does the psu data sheet tell? maybe the psu isn't big enough for the new card.

The PSU just barely refuses the card, need to buy a new PSU I guess.
