Ok so that post got me thinking. I tried the GPU in the second PCIe slot and low and behold it's working. So my primary PCIe slot is gone, nonfunctional. Crazy because I believe this to be a pretty rare case, anyway just thought I'd mention it in case someone in the future might search for this or something similar.
Now you know that testing both PCIe slots is viable and that a primary PCIe slot can stop working. Glad we all learnt something today :-)
Now the next problem is the space in my M-ATX setup is so limited this damn 6990 doesn't fit here. Tested using the gt 7400 because I didn't wanna dismantle my whole PC.
Ok I don't know what the hell is going on here, I switch on my PC after about a week and I get no display, "no signal". I tried different display inputs DVI and mini display port still nothing with different cables. Tried a different older GPU (Nvidia GT 7400) known to work in my set up and still nothing (DVI & VGA). Went beyond and tried a different monitor with both GPU's, again nothing. According to the Q code on my motherboard it reads "A0" which indicates normal functionality. I tried clearing CMOS and flashing the BIOS to different versions still nothing. Please help I don't really wanna go out and buy new hardware.

Yeah I vote for memory leak ^^
Edit:
You can try re-downloading and installing windows, or wait for an update to fix it? Also do a quick search and see if it's a common issue.
Well this looks to be pretty much done, I'll throw this in anyway, the screen quality also looks a bit bad to be original. Honestly OP, look for a reputable seller and pay a little more, tomorrow you wont be disappointed.
Try bringing the router closer to see if it's a range issue, maybe use a wireless range extender as well. In my experience those wifi cards are a bit dodgy.
