Computer Randomly Shutdown

I am currently having trouble with my computer, it shutdowns at random times. Let me start from the beginning, it all started when my PC started to crash and gray lines appeared on the screen. It usually happened when I tried to multi task. It happened so often I decided to test my PSU and everything looked fine. As soon as I was done testing it I plugged everything back in and my PC would not turn on. I left it off for a few hours and after that it turned on and I was able to use my PC like normal so I had thought it was fine. After I was done using it I turned it off and went to sleep. What is funny though is before I shut it down and went to sleep the PC had been on for at least 10 hours. The next day I was able to use it for a few minutes then it shut downs out of nowhere. Once it is shut down I am not able to turn it back on unless I unplug my PC and plug it back in. I can turn my PC on but it shuts down after a few seconds. The longer I leave it off, the longer I can use it. One time when it had shutdown I turned it back on and the graphics were scrambled and green, it shutdown. It is no longer doing this. At one point a few months ago I would be playing DayZ and it would shutdown. It happened a few times and after that it never happened again for a few months. What I would like to know is what could be causing this. I checked all of the temps and everything is ok. Btw, I had used windows loader before all of this and uninstalled it and ever since, this has all been happening, not really sure this would make a difference.
P.S. a few times when I tried to turn it back on the CPU fan would not start and nothing would start except for the case fans, GPU fans and HDD indicator would be at a constant. It no longer does this.

PC Specs:
AMD 6300 (Stock cooler)
2x ASUS 7870 in crossfire
ASUS Crosshair V Formula Z
8GB GSkill RAM
OCZ 750W Modular PSU

I tried but it did not work. In that link you sent me it said to make sure GPU was in properly and I remember when I was building the machine it did not look like the GPU was in the slot all the way so I tried putting some force onto the GPU but I felt like I was gonna break it. So I think the GPU is not making proper connection and I am gonna try to reseat the GPUs
