the graphics card is a cheap one , but will do. De frag game?

Try waiting for it to load.
If you have a slow hard drive, it can take a while.

get a ATI (AMD now) Radeon. also downgrade to XP I run GMod on XP it never crashes. do a defrag and (or) virus scan. if you have had GMod for a long time check your LUA folders for LUA viruses.

Wait, Just wait. Do not click so much. Play in fullscreen, and you won’t even see this.

You don’t need to freaking downgrade, It is not a freaking virus. If you want, you can upgrade.

No, you don’t downgrade to XP.
Just be patient and wait for it to load.

Simply, When gmod loads, Get the fck out of your computer and watch tv. Watch TV until GMod is loaded, Do not press any key.

Nah, Just play in fullscreen, and you won’t even see it crashes. It is simple as that!

Launch it in windowed mode.

No don’t thats what causes it to go black then white when you click it again, if that happens you just wait.

Learn english, than ask people.

Here’s my epic answer for you.
