Frozen Splash Screen!

Continuation of my previous build, different issue.
SORRY FOR LONG POST, JUST TRYING TO DESCRIBE PROBLEM ACCURATELY.
PICS INCLUDED.

Basic Parts:
1 x GIGABYTE GA-B75M-D3P LGA 1155 Intel B75 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
1 x Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics ...
1 x G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-
1 x COOLER MASTER HAF 912 RC-912-KKN1 Black SECC/ ABS Plastic ATX Mid Tower Computer Case
1 x EVGA 02G-P4-2645-KR GeForce GT 640 2GB 128-bit DDR3 PCI Express 3.0 x16 HDCP Ready Video Card
1 x CORSAIR Builder Series CX430 430W ATX12V v2.3 80 PLUS BRONZE Certified Active PFC Power Supply

I got the computer to POST with a motherboard & CPU & fan and one RAM in one slot and then we were able to POST with RAM in slot 1 and slot 3 (one white, one blue -- which is not which is not what it says to do in the manual but no other RAM configuration worked)

I also POSTed with the graphics card in place and DVI out of the graphics card.

Since that test boot worked and I could reach the BIOS, then I proceeded with the rest of the peripherals; I added a SSD, a HDD, USB internal hub port, Wi-Fi card:

1 x Crucial M4 CT128M4SSD2 2.5" 128GB SATA III MLC Internal Solid State Drive (SSD)
1 x Seagate Barracuda ST31000524AS 1TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
1 x TP-LINK TL-WDN4800 Wireless N900 Dual Band PCI Express Adapter, 2.4GHz 450Mbps/5Ghz 450Mbps, IEEE 802.11a/b/g/n,WEP, ...
1 x SYBA SY-HUB20076 USB 3.0 Internal Hub 4-port, Ffits Both 3.5" & 5.25" Bay

Once I added to the rest of the peripherals attached them to the motherboard and powered them it POSTed and I got the gigabyte splash screen (which is correct since now the hard drive is attached) --but it appears that the USB is no longer working so that the GIGABYTE splash screen comes up and we are unable to navigate anywhere on the screen -- and the caps lock light on the USB keyboard --(usually a good test of USB connection) is not working.



I plugged the keyboard into all the USB ports with no luck. (including front panel)
I am unable to navigate beyond the gigabyte splash screen.

Since that failed -- and I believe the USB is not working;
I stripped the system down to what was working before (when i could reach BIOS screen) with the hope of building back up, but now I cannot recreate the quick POST of before with the stripped down system.

as far as we can tell, the USB is not working.
the systems POSTs but it takes significantly longer than the original test boot configuration.

also, the GIGABYTE splash screen appears -- and no working keyboard.

the question on my mind right now
IS MY MOTHERBOARD JUNK?
