[Resolved] System No Longer Powers On???

[billybatson]

I built this system 2.5 years ago and it has functioned perfectly so far. It was working fine until 3 hours ago when I unplugged everything so I could take it outside and blow out the dust with air in a can. I brought it back and plugged everything back in but the system no longer boots. When I plug in the power cord in the network light on the back flashes once and on the mobo itself the standby light and dram power light are both on. Using the external power switch or the power switch on the mobo itself causes nothing to happen.

 

I unplugged amm the HDDs, dvd drie, took out the video card, and still nothing. Was thinking maybe something was causing a circuit to be jumped r whatever. On the back there is NOTHING connected but the power cord.

 

What could be it? I work 15+ hours a day and don't have a day off until Thursday so I do not have the time to compltely take apart the system and rebuild it and have it still not turn on.

Sounds a lot like a PSU failure.

 

Your 480W is borderline to begin with since the recommended PSU for the DFI NF4 is min 480W native 24-pin.

Another possibility would be that the air compressor had moisture in it and you blew water onto your components

radodrill you were right. I went and purchased a new PSU and the system now boots fine. I think you and Momoceio were both right, I have never had problems with the air in a can and moisture before but I did spray the can at an angle for a second while blowing out the PSU and that must have done it somehow.

The 480w PSU was fine throughf or what I was running. I purchased a 700w but not the best, Rocketfish (best buy brand) since my discount reduced it from $170 to $58 lol. It is temporary especially since it is quite loud.

thanks again
