No POST or Video Display - Newly Built System

Greetings Tom's Hardware forum base.

The subject sums it all up, except for one thing being that this is a newly built "bare bone" system.

My Newly Built System Story:
When I first built the system it booted up flawlessly, managed to boot into an old HDD that included a fully functionally OS, Windows 7 - 64 BIT. When I first booted into Windows I decided to update my MOBO drivers via MSI's supplied 890FXA-GD65 CD. I updated as many of my drivers as possible before I actually restarted the system. I restarted, entered my BIOS utility to change my boot-sequence because it was not set correctly. I changed the order to what I want set and right when I was about to save the BIOS settings my display goes BLACK, the power LED turns orange and I currently have no display. The
computer was still powered, HDD still seems to run, CPU fans spin, GPU fans are spinning. I couldn't power down the system with the tower switch and had to switch off the PSU itself. Very unsure what caused this instability. Im stuck at this point, I can power up my system, all fans run fine, but I cant get it to POST, BEEP or show a DISPLAY.

My New System:
*MSI 890FXA-GD65 AMD Socket AM3 Motherboard
*AMD Phenom II 1100T 3.3 GHz Black Edition Six Core Processor
*Kingston 8GX Memory - 16 GIG PC3-12800, DDR3-1600MHz, 240-pin DIMM, 9-9-9-27
*PowerColor Radeon HD 6950 GPU - 2GB, GDDR5
*Cooler Master Silent Pro M 700W Power Supply - ATX, Modular, 700 Watt, 80+ Bronze Certified
*Cooler Master Hyper N520 CPU Cooler (AM3 Compatible)
*NZXT H2 Classic Silent Mid Tower Case

Steps Taken (Trouble-Shooting):
* Checked for possible shorting on case to MOBO - doesn't seem like it was
*Tore my system apart and bread-boarded it onto a cardboard sheet (MOBO, CPU, PSU, GPU, 1 Stick of ram)
* Reseat CPU - no POST or VGA
* Remove all cards and boot - no POST or VGA
* Remove all RAM & cards - no POST or VGA
* Checked all power connectors are in and cleared CMOS using MOBO button and ALSO the jumper technique (move from pins 1 + 2 to 2 + 3 and back again) - no POST or VGA
* Tried using an old GPU (GTX 9800 pro+) - No Display or POST
* Tried an old 500 Watt PSU, isn't rated to handle my system but I tried booting the system with the GPU to just try and produce a POST - No Luck

Other than the 8 PHASE LED configuration I dont understand outside of the manual's description. When I turn my system on the LED's all light up (right away) in this configuration:

[1-on] [2-on] [3-on][4-on] [5-on] [6-on] [7OFF] [8-on] (The 7th LED in the string is off while all others are on - do these indicate anything?).

I dont know where to go or what to do at this point other than RMA'ing some products here. I am still uncertain if it is my MOBO or a failed CPU? Please will any of you TomsHardware Masters enlighten me on what could be wrong here!?

Thank you all so very much in advance.

Best Regards,

  1. Bumping this one time to try an elicit a response. :(
  2. Have you tried installing a fresh copy of Windows?

    Your hard drive already had a sets of mb drivers installed . Having two sets of mb drivers might be the cause of the problem
  3. Hey Outlander,

    I thought about doing this. But how does this explain not being able to get a video display, post or beeps when I have my system bread-boarded. Bread-boarded meaning I only have my MOBO, CPU, GPU, PSU, CPU COOLER and 1 Stick of Ram running outside of my case. Nothing shorting, etc etc.
