AMD Radeon HD 7770 GHZ Edition Resolution incorrect and computer hangup

Question

Hello all. I have been chasing down a problem with my computer hanging up when playing CS:GO. The computer will freeze/lag and repeat the previous 1second of audio/video until I hard boot the system or pull power. I updated my BIOS version as well as installed all of the most recent drivers for both MoBo and Catalyst Control Center.
My build specs exactly:
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor ($199.99 @ Microcenter)
Motherboard: ASRock Z87M PRO4 Micro ATX LGA1150 Motherboard ($99.99 @ Newegg)
Memory: Patriot Signature 8GB (2 x 4GB) DDR3-1600 Memory ($52.99 @ Newegg)
Storage: Samsung 840 Series 120GB 2.5" Solid State Disk ($90.99 @ Amazon)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive ($59.99 @ NCIX US)
Video Card: MSI Radeon HD 7770 GHz Edition 1GB Video Card ($69.99 @ Newegg)
Case: Fractal Design Core 1000 USB 3.0 MicroATX Mid Tower Case ($29.99 @ Microcenter)
Case Fan: Arctic Cooling Arctic F9 43.0 CFM 92mm Fan ($4.98 @ Amazon)
Power Supply: XFX 550W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply ($45.99 @ NCIX US)
Optical Drive: Samsung SH-224DB/BEBE DVD/CD Writer ($15.99 @ Microcenter)
OS: Windows 7 64bit Home Premium
When I initially installed the video card and set it up, I had set the resolution to MAX which is 1920x1080 (my natural ASUS LED monitor's resolution) but got a black border around the desktop screen. I didn't think much of it and just reduced the resolution to something that fit better (dont exactly remember the size) but in an effort to troubleshoot the problem, I removed the video card and ran the monitor off of the MoBo HDMI output. When I set the resolution to 1920x1080, the desktop fit perfectly.
What would cause the same resolution settings from the HDMI out on the MoBo and HDMI out from the video card to display differently?
I completely uninstalled CCC and reinstalled the driver and there is no change in the difference in resolution display.
Some things I tried to diagnose the hang-up problems:
MemTest86+ on both sticks of ram for 10+hours without an error
Prime95 for 4+ hours without an error
FurMark ran at 17FPS at the reduced resolution for 20+ minutes sitting at ~60-62C steady state without a hiccup
CPU and GPU temps are always in check, never reaching past 65C under full load. I have not overclocked anything or adjusted the performance of the system. It is really frustrating and I am wondering if the 2 problems are connected somehow.
Any help on the resolution issue would be fantastic!

for the black border via HDMI that's normal as it will have scaling on 10% by default!
1: go into the AMD software
2: expand My Digital Flat-Panels
3: go to Scaling Options (Digital Flat-Panel)
4: change the scaling from 10% to 0% and apply
now it should fill the whole screen at 1920x1080 resolution!
Ill try that when I get home! Thanks!
Just out of curiosity, why would the scaling be down 10%?? That seems kinda silly!
