Computer Problem/Artifacts with lines and bars/Blue Screen/Resolution

Hey guys. I've been having computer problems lately. The main problems are colored artifacts, Blue screen memory dump, Resolution change after restart. This happens when I play video games or watch movies. On the blue screen Its says video tried to reconnect but failed/ timed out. I have replaced the Power supply, Video Card, and Ram with no fix.
Earlier I had no signal on my screen and was not responding. I tried the integrated graphics and the same thing happens. I also did a hardware test on my CPU, hard drive and ram and they all passed. Most likely its the motherboard but I need to be sure. Hell I should just build another computer with the previous parts. ( Except the mobo )  

Oh yeah the link. My reaction to this problem....
