Given the size of the power supply, that would be my first suspicion. 6990s are dual GPUs and VERY power hungry. Would have thought 600W would be OK for a single card tho...
Might be worth checking nevertheless.

good thing yours doesn't experience blue screen of death. 
What's your GPU and MEM clock? also your voltage?
Try Multiminer or Guiminer. It helps your for a start.

Hi guys,
new on the forum. Hoping someone can help me out. I had a 7970 in my pc and in the process of changing hardware so that I can mine Litecoins. The 7970 works fine. Now I installed 1x 6990 and it doesn't do anything. I tested it in my other rig and works fine.
So first let me explain with GUIMiner:
Host: ltc.give-me-coins.com
Port: 3334
Username: ****.1
Password: ****
Thread Concurrency: 8000
Worksize: 256
Vectors: 1
Intensity: 13
GPU Threads: 1
When I say start the console only shows this:
Running command: "C:\guiminer-scrypt\cgminer\cgminer.exe" --scrypt -u ****.1 -p ***** -o stratum+tcp://ltc.give-me-coins.com:3334 --gpu-platform 0 -d 1 -w 256 -v 1 -I 13 -g 1 -l 1 -T --thread-concurrency 8000
Listener for "LTC Mining" started
and in the summary screen this worker only shows up as connecting?
Now via cgminer. This is my script:
C:\cgminer\cgminer.exe --scrypt -o stratum+tcp://ltc.give-me-coins.com:3334 -u ****.1 -p *** -I 13 -g 2 --lookup-gap 2 -w 256 --thread-concurrency 20992 --auto-gpu --temp-cutoff 95
the cmd box will open and show
"
Started cgMiner 3.5.0
"
and then it closes. No errors or anything.
Like I said it, with my other rig with the same settings and the same router it works fine. The only difference between the 2 pc's are the OS and the motherboards. PC that it works on has:
Asus board
650w PSU
Windows 7
PC it doesn't work on has:
Gigabyte board
650w PSU
Windows 8.1
I've tried several things but nothing seems to fix this. Please assist as I'm looking to get more 6990 GPU's
