Motherboard slots stopped working after using compressed air

[Jennings99]

After using compressed air to clean out the the computer, I tried to power on my pc and it would turn on for 2 seconds then go off.

I then unplugged it all and re connected the PLED switches on the motherboard, it then powered up fine.

After it powering on I realised no lights came up on my keyboard or mouse, and no display on my monitors. No ports on my motherboard are working but yet everything powered on correctly I just don't have anything external working. Any ideas?

My display is hooked up to my MSI GTX 970 which still shows no display, the cards LED lights up at the front constantly and the fans spin for 30 seconds until stopping which is normal.

Try re setting BIOS!

It could be your mobo I could of died in the process the you make sure there no power going to the pc like when you pull the plug did you turn it on to make sure all of the powers gone from the system

@rolli59
I just tried that and it did not work

@ComputerTechKid14
The PC powers on completely fine and everything runs perfect, it's just I have no access to any devices plugged in via USB or no display from GPU

 

[ComputerTechKid14]

Do you have an old pc laying around you can try to make sure all the wires leading from your case to your pc you can try your gpu in another pc if you have one

 

[ComputerTechKid14]

Try using onboard graphics because your mobo might of switched to onboard graphics instead of using your gpu

 

[rolli59]

Are you sure you are plugged into native USB ports? Some may have to be activated in BIOS.

@ComputerTechKid14

I didn't really understand your first message, if you mean do my equipment work in another PC then that would be yes. I also tried using onboard graphics but still no luck as the PC boots but I can not see anything on screen or keyboard/mouse do not light up

 

[Jennings99]

@rolli59
None of my USB ports are working at all but for some reason my USB headset adapter does light up but the headset isn't powered on because usually I can hear myself through the headset but I can't

 

[ComputerTechKid14]

Do you check your 24 pin cord or 29 pin cord make sure they are in fully

 

[Jennings99]

@ComputerTechKid14
Yes, that is in correctly because if it wasn't in then the PC wouldn't boot at all, mine does boot I just can't see anything on screen.

 

[ComputerTechKid14]

If everything works fine it could be your power supply

 

[ComputerTechKid14]

Cehck all your cords like your 4 pin if not its your power supply or motherboard

 

[Jennings99]

@ComputerTechKid14
I didn't unplug any cables so I can only assume that i must have damaged something when the liquid made contact with the GPU and Motherboard

 

[ComputerTechKid14]

Yet. That is possible you can also check your capacitors on your mobo make sure there attached had this problem last time. Yes the liquid can make contact did you shake the bottle when you did this a couple time when spraying?

 

[Jennings99]

@ComputerTechKid14
Yeah I think so as liquid did come out of the can making contact with my GPU fans, how can I check my capacitors on my ASUS Z97-A?

 

[ComputerTechKid14]

Check if there's leaks and under the capacitator if it's hits your gpu take your gpu out and use onboard graphics

 

[ComputerTechKid14]

If it doesn't work the I don't know what will

 

[rolli59]

reseating everything is the next step all connectors and cards, including ram modules.
If that does not help most likely your board gave up.
