“I decided to go on singleplayer one day and it crashed at the end of the loading menu. No warning, the screen went black as a stone. The lights for my monitor and computer itself were still on, but the light for my keyboard was off. I couldn’t use task manager, I couldn’t even see my cursor. Turned off, and on. Happened again after 20 seconds of running around city8 with a crowbar and jumping. Turned off, and on. Happened at the menu of RPwars (this time the screen was a dark shade of blue). Turned off, and on. Happened again in RPwars (this time the screen went an interesting shade of peach). Turned off, turned on. Turned off, and on again.
I uninstalled garry’s mod from steam. It was still there so I had to delete the folder manually.
I reinstalled garry’s mod. No success.
I reinstalled again. This time it started on 90% - When it was complete I couldn’t find the folder anywhere.
I reinstalled again. This time half of the folders were missing - There was no update for garry’s mod, and the maps were missing.
I reinstalled again, and played. No success - It crashed on the loading screen.
I then got bored and player counter strike.
I then decided to scan for viruses using Norton. No viruses.
So, I decided to reinstall steam. No success. Although I managed to get in a good game of Sim City 4 while steam was installing.”
I posted this on another thread in another forum. One of the users on the forum said it is probably a virus. So have you ever come across a virus which makes your gmod blackscreen like this? Help would be much appreciated.
