Where I work, we have a couple of MSI Windtop touch screen desktop computers. They are not that old... maybe 2 years at most? They are also not used that much, and as such, not abused in any way. Well, both computers all of a sudden out of nowhere are giving this "VGA No Signal" error when you turn on the computer and then the message quickly goes away and the screen just remains black. The one I am currently in front of, you can hear the fan inside of the computer running and it is running louder than usual. The green power indicator light is on and stays on on the bottom of the screen as it should when the computer is turned on, but that's the extent of the operation ability of these computers right now. What is going on with this? Also, there is no way to plug in another monitor since the only input ports that the computer has are: four USB ports, one ethernet port, one memory card port, one microphone port, one speaker port, and the power port. Is there anything I can do to fix this? Any help would be greatly appreciated.
