Yellow circle!? Cant get rid of it!

Ok i had uninstalled and reinstalled Gmod over 8 times and this yellow circle (almost like a cross hair) Stays in the mideal of the screen I cant even see the tabs that are sapost to be on the top of my screen. And I have a feeling this yellow ring thing keeps me from seeing it. even taking pictures it gets in my ay. How do I fix this? this is what i see. http://cloud-2.steampowered.com/ugc/921266377333742817/B1A3AF7D89C091A0BE6E184A0A1CBC1E5BC9B4DB/1024x479.resizedimage

Does this only happen on one server?

its on every server i join! its like its stuck like that.

unsuscribe to all your addons, unistall gmod from steam, then go into the common folder of steam and delete gmod manually, then reinstall gmod, go to an included single player map, and see if its still there

“exec undo360controller” in console.
