I just purchased a TX750 V2 PSU, 4 gigs of ram and a GTX 560 to upgrade my computer. When I installed everything the computer worked great. Fired right up. I used the computer fine for about a week then when I went to turn the computer on it lit up and started then turned off maybe 5 seconds later. I then checked to make sure that all the wires were seated properly and they were. I then turned the computer on, it turned off. I unplugged it, then plugged it back in and it ran fine. I was able to be on it for about 3 hours. I then turned the computer off cause I left the house. When I came back about 3 hours later it started then turned off immediately. I then opened it up and checked it and now sometimes I hit the power button and it doesn't even start. Is it my power supply? or should i take the PSU out and then plug it back in? I don't know much about PSU's please help
 
ih you have any other power supplies try them, if you have to then remove your gfx card too so it will have enough power to run everything
