First time user.Running windows 7, Arduino Uno plugged into USB port in front of computer. Light blinks on-off. Using Arduino 1.8.7 software wrote code to make blink per tutorial, when I attempt to upload I receive this error(problem uploading to board),see attachment. Under tools/ports,it shows ports 3,4,6,8,18, none with Uno attached. Have no idea of port # I'm using, checks with device manager no help. So I attempted to upload using one port at a time,all with same results. Must figure this out before attempting anything else.
Is it a CLONE baord or a true Arduino ?
If it is a clone you may need additional drivers either CH340/341 or CP 2102 etc.
What does device manager actually show when you plug in the Arduino as a port number will appear if the board has the correct drivers ?
When posting errors please use code tags ( </> ) as pictures dont always do justice to the error.
Scrubbed and reinstalled program,this is the error message in full. Here is attachment in full with error message.

So device manager COM ports did not change when you plugged in the Arduino ?
No bing new hardware sound made ?
If that is the case you may have a dead board.
Looking at your COM port list it is also feasible that you have some other software that is interfering with the Arduino com port detection.
Not being at your side of the screen it seems odd that you have two RIM devices and all the other ones.
Not sure what a RIM device is, but I only have maybe 4 ports, two up front, one goes to wireless mouse, one free that the UNO is plugged into, a printer and maybe a wireless wifi in back.
The UNO blinks as soon as it's plugged in, which surprised me as I was expecting to write that code as lesson 1 in my tutorial.But I assume the blinking means it works?
I have some drawing programs as well as recording software ,as well as the usual antivirus ware, what type of program might cause a problem?
See your screenshot as I doubt they are all the devices you mentioned.
Not seen wireless devices masquerade as COM ports for a very long time (years)
At the very most you maybe should have two/three devices showing as COM ports
There seems to be extra almost duplicates with your RIM device and Sierra devices.
Blinking is normal as you rightly guessed as almost all boards come with that installed.
Mt bad,the wireless is not a usb ,but something that looks similar.Still trying to figure out what a RIM device is.
The RIM device might be a mobile phone but if it is then you may have a quite old Blackberry device. (made by RIM)
It may be worth resetting the COM stack in windows.
During the operation you may be asked if you want to also UNINSTALL the drivers.
Normally I would say no but in your case I would probably say YES.
Clearly you would have to unplug as many devices as possible during the reset.
The once the stack is cleared plug only one device in at a time until the driver has been re-installed.
You may want to start with the Arduino first so that there is a good chance the driver takes precedence. (hopefully)
