Mac Pro :: Red Light On Riser Card

Yesterday, I unhooked everything from my MP to install the following: 2nd superdrive, 2GB RAM stick, Intel SSD, stock Nvidia GT120(slot 3). Now, I have since taken out the additional RAM because testing showed faster memory tests with 3x2GB ram sticks vs 4x2GB. I'm assuming because of tri-channel memory. Anyway, now when I cut the computer on I'm getting a brief red light flash on the riser card. I have looked in system profiler and it shows all DIMM slots as "OK" and is showing 6GB of RAM. I have inserted the OSX DVD and ran a short and long hardware test and nothing shows up wrong or problematic.

The computer as you can tell in my other thread about SSD benchmarks is running at great speed! The only true weird thing is when I tried to boot from the OSX DVD to restore from a time machine backup on the Intel SSD, the MP hangs up on the grey screen with the apple logo(spinning wheel is there but freezes eventually) and on my second monitor is shows a box that says "You need to restart your computer". So this is a kernal panic, no? The nearest Apple store is over 2 hours away and the same goes for an authorized shop.

Also, I installed the stock HDD and the factory RAM and the light still remains. The only way I could use my SSD was to use carbon cloner and put the SSD in bay 4 and go that route. Everything worked fine and the SSD is now the boot drive. But, its kinda irritating because if this thing fails I can't boot from the OSX DVD to restore. The only thing I haven't done is remove the Nvidia GT120 but I had to re-install that crappy thing because I am running 3 monitors now. I have my main monitor(dock) hooked to the GTX285 and monitors 2 and 3 running of the GT120.
