Accidentally uninstalled wrong driver now no display -

Ok I am leaving this to the others as in my mind unless the machine has a dedicated GPU as well as the Intel graphics as in my gaming Asus - then the GPU is an NVidia installed as a part of the original build and in probability soldered to the board.

I still don't know how you are connecting the external monitor to the machine and it could be something as simple as a cable issue but anyway good luck with the problem.

OK everyone! I feel not so smart right now, but am relieved, because yes, the monitor was not selected and using fn-f4 solved it. The mouse and keyboard work again after re-installing the driver. Thank you all very much for the help I really appreciate it.

ICIT2LOL I did say I attached the monitor the vga port. This laptop does have overheating issues with the graphics card and I have had it apart and seen it it is a separate chip soldered to the board, and I do have some other display issues but have workarounds for now. Thanks for your ideas.

By chance to you happen to know how to fix an 'unable to find com port' error?
That is the root impetus for my uninstalling the USB drivers. After all of this, the condition continues.

I have an arduino uno , and it often gives me the error that it can't find the com port when I attempt to upload a sketch - it doesn't matter which port I select for it in device manager. It does detect the port because the port number I choose shows up in the ide, but when I go to upload a sketch it always says it can't find the com port.

I think it's related to a Bluetooth USB dongle I have used intermittently it always creates 3 ports and one one them always has an error in device manager that I have been unable to resolve. Other USB devices work well though, including an HTC phone that generates a com port and an external HD. It just doesn't like the arduino for some reason and I don't know enough about windows com ports. So I uninstalled all of the csr Bluetooth USB dongle software and the phone sync software and went on trying to delete USB related drivers in device manager. But even with all of that completed the problem remains the same. Any suggestions or ideas are welcome.

Thanks.

My apologies for that.
