Gmod locking up pc on sending client

Gmod locking up pc on sending client Info my specs are

Intel® Pentium® CPU N3530 @ 2.16GHz

Video Card Intel® HD Graphics

RAM 4.0 GB

Operating System Microsoft Windows 8.1 (build 9600), 64-bit

If it just locks up for a while and then works, then that is completely normal. My game always stops responding while it loads for a little bit.

If you run Garry’s Mod in windowed mode, you can click elsewhere and do something else while you’re waiting for Sending Client Info.

no it locks up my pc and i have to restart
i tried in windowed mode yesterday

try adding -windowed -noborder in the launch commands for garry’s mod, it’s really nice
