Hi,

I use air compressor to clean dust inside my desktop, at first I plug in the power plug it boot up and the screen say please plug in the additional power plug to the graphic. I press the power button to shut it down, after insert the extra 2 pin to my gtx960 my computer wont turn on anymore. The orange led light on my motherboard is offline, go buy new power supply and it still wont turn on, after leave it for 40 minutes the orange LED light on motherboard is on again but the computer wont turn on, after touch the reset cmos the LED light turn off. I did remove memory, graphic card and sound card still nothing. Any suggestion? Did somehow the compress air got wet my motherboard when I tilt the can and then when I turn on the computer it fries?

CPU: i7 3600

Try the breadboard test, take your mobo out of your case and place it on top of a cardboard box, like your mobo's box. Keep only 1x RAM module and CPU and connect it to your PSU and see if you can get a successful boot using your integrated GPU.
