Hi, i decided it was time to clean the desktop so i pulled off the side panel and usb a can of compressed air all over it which was working fine untill it randomly started spewing out liquid! it got all in my front usb ports and now they dont work, I get 0 power from them. could anyone tell what ill need to do to get them rocking again please? the rest of the pc seems fine and im using a coolermaster haf 912 plus. thanks to anyone who can help
