So I just got this computer my brother built for me from his house and It was working fine over there after windows was installed so I unhooked everything and Put it in my car. I brought it home and it was raining outside when I ran it to my car from his house. I brought everything inside got it set up and the computer worked fine other than it wasn't putting out a signal to my monitor so I unhooked it turned it everything off and put it on the floor. I opened the side up to see if anything was unhooked and There was 1 power cable from the Graphics card unplugged so I connected it but kept the side panel off so I hooked everything up and I pressed the power button but only a faint blue light flashed for a split second and nothing was happening so I unplugged the cord I plugged in from the graphics card and the same thing happened. So I moved the cord to the power supply over to a different outlet and nothing happens but a flash of blue. So I pressed the power button down again and nothing happened not even a flash of blue so I Got a different cord to the Power supply but nothing happened, I tried flicking the switch back and forth on the PSU and pressing the power button each time. I'm kind of stumped because it turned on a second ago just with no output to the monitor but now it wont even turn on. Any help I can get would be much appreciated.
