FAST GAMING PC Intel i3 sec gen 8GB DDR3 1 TB HDD 2GB GDDR5 Graphic Card Win 7

Hi i have the above gaming pc.lately it would turn on but the screen would not come on.sometimes a few goes turning on and off the screen comes on. Today i can get it on at all.i removed the graphics card and connected vga to motherboard and the pc turn on for about 30 secs no screen tho then turns it self off and then on again.i put graphics card back in and connected vga to graphics card still no screen coming on.any ideas is the graphic card --- or could it be a faulty vga cable or something else
 
If system does not work properly even on the onboard video, could be a failing power supply or motherboard. Did you test the monitor and try another cable? Not likely those are the issues, but you need to rule everything out. What is the power supply brand and model?
