Graphics card not recognized, I've tried everything!

I've got my first build all finished, all drivers installed and ready to go (I'm even posting this from the new build) except my computer will NOT detect my graphics card! I've tried removing it and putting it back in countless times, I have checked over 2 dozen times that the power cable is correct; I've tried it in my buddy's computer and it worked fine (his card did NOT work in mine, it was the same model); I've tried using the disc it came with however when I try to install the driver installer it gives me a message saying I have an incompatible build; I've tried downloading and installing the same drivers from the web, and that works, however when I boot up the computer it will display the windows loading screen (you know, that colorful one) but go black when it reaches the login screen. My only last idea is that my motherboard's pci-e slots simply do not function.

I think that's all of it, I may have missed one or two things I tried, but let's start from here.

My build:

Silverstone Strider 750 Plus 750W Modular Power Supply ATX 24PIN 135mm Fan 60A 80+ Silver Black

Microsoft Windows 7 Home Premium Edition 64BIT SP1 DVD OEM

VGA POWERCOLOR|AX7850 2GBD5-DH R

AMD FD6300WMHkBOX FX-6300 Six-Core 3.5GHz AM3+ Processor - AM3+, Six-Core, 3.5GHz, 14MB, 95W, Unlocked

MSI 990FXA-GD65 V2 AMD 990FX Motherboard - ATX, Socket AM3+, AMD 990FX+SB950 Chipset, 2133MHz DDR3 (O.C.), 6x SATA III Ports, LAN, USB 3.0, RAID

WD Blue WD2500AAKX 250GB Hard Drive - 3.5", SATA, 6Gbp/s, 7200RPM, 16MB Cache

Lite-On IHAS124-04 Internal DVD Writer - DVD+R 24X, DVD-R 24X, DVD+RW 8X, DVD-RW 6X, DVD+R DL 8X, SATA (OEM)

Patriot PXD38G1866ELK Viper Xtreme Performance Desktop Memory Kit - 8GB (2 x 4GB) PC3-15000, DDR3-1866MHz, 9-11-9-27 CAS Latency, XMP Ready

VisionTek 900511 Go-Drive 120GB SSD High Performance Solid State Drive - 120GB, SATA III, SATA 6.0Gb/s, 2.5"

I sure hope you guys can help me! I've got nothing to do for few days so...I'll be watching this thread like a hawk.

It sounds like your having a compatibility problem but cpu, mobo & gpu seem good. Check power to gpu with malty meter? Check all power connections to make sure they are secure? Check mem chips to make sure they are secure and compatible?
List every component by Brand & Model including OS…

My BIOS does not have the setting to do that, it can only change the latency.

Everything is plugged in properly, and I'll edit more detailed specs into the OP

Update: My friend's old 7750 works fine, contacted the motherboard manufacturer and everything is kosher with my video card so the only remaining idea I have is to contact my video card's manufacturer and see if there are driver problems.
