Thread: Going all out

I started having a similar problem and it went away after I updated my graphics driver.

ive done everything suggested

#Update Graphic Drivers (which ill do again)
#Verify Game Cache
#Check Fan Speed (are fine)

but still no luck

I had this issue a long time ago with the L4D2 demo (and later a few times with the full game), it worked fine for a few days and then suddenly I got the black screen you described, although my computer didn't crash...

I fixed the problem by doing a full re-install, going into Steam\steamapps\common\left 4 dead 2\left4dead2 and deleted all the left over files that were there after uninstalling the game through the steam gui.

Hope it works for you.

Having read the last comment I'm reminded that I also went through the same process.

I have an old Nvidia 6800gt card transplanted to a quad-core server class box. I think the graphics in the game, and going from a 32bit to a 64bit, outstripped my cards ability to function. But during that process I also did all the usual stuff mentioned above and it still crashed my system.

With the latest driver it worked.

I bet it was because it was a beta 64bit driver I originally installed to the quad-core. I finally install the official 64bit driver and it worked.

Sorry if I led you astray.

No, I see what you mean i just installed the official Galaxy Geforce GT240 (which is my card) and i will test once im done re-installing!
