2 Gmod Problems

My first problem is that whenever I join an RP server or any server actually, whenever I press tab to see the scoreboard, nothing shows up. Just long ovals with color, no names or anything like that.
My second problem is that every time I quit Gmod, my game becomes frozen and so I have to restart my computer.
Help would be appreciated

For your second problem I think you have to be patient on my old computer it took forever to shut down garry’s mod but I just waited. Also what your doing could be corrupting your hard drive by restarting that much… can you access task manager turning garry’s mod shutting down?
