I installed fallout 3 the other day and about 15 min in the screen starts to turn green and it freezes. I went to fallout forums to see if it's a problem with the game. And it appeared that it was for some people. Some of the solutions were to reinstall drivers, disable ffdshow audio/video decoders, playing in windowed mode. None of that seemed to work. I uninstalled Fallout 3 and figured Id wait for a patch. Here's the big problem. All the games I play that worked before I installed fallout 3 do the same thing now. Sometimes they freeze right away and the screen goes black and I alt+tab out and close it. Sometimes the screen will turn green and freeze(with audio still going). Sometimes(rarely) the game would run for a couple hours with no problems, until lately. Ive tried: *Uninstalling drivers, using driver cleaner(safe mode) and reinstalling with my AV turned off. I've tried older drivers and brand new drivers. I've done the same with my audio drivers. *I've reinstalled directX *I've dusted my entire rig. *I monitor cpu/gpu temps and use rivatuner and all temps are at acceptable ranges. *I use ATItool to overclock my GPU and I've tried running at stock and underclocking. (When I scan for artifacts with ATI it freezes almost immediately now, regardless of the clocking. At least that rules out audio issues). *I've updated my MOBO chipset drivers. *Windows is up to date. *I've cried myself to sleep. Out of about 30 crashes over the last few days, a couple times early on I got a message that my nv4_disp driver crashed. But 9 times out of 10 it just freezes with audio and I'm able to alt+tab out after a minute or so. Maybe if I just sat and waited I'd get the nv4_disp message more, I don't know. But I haven't seen the BSOD yet, thank god. Could this be a secuROM issue? I have other games with secuROM. All my games (COD4&5, RSV1+2, Dead Space, Far Cry 2, The Witcher, Gears of War and many more) worked perfectly until I installed Fallout 3. The only solution I can think of is to get a new GPU, or at least try it in someone elses rig. I might try reinstalling XP too. Anyone have any ideas?

YES Ever since I installed fallout 3 every game started crashing! I've done EXACTLY everything that you listed to try to fix it too (including crying myself to sleep) At least I know I'm not crazy. Maybe we'll have to format :(

Hmm interesting. I'm surprised anyone can play fallout 3 smoothly. I deleted the older version of C++ 2005 I had installed(I had 2) and updated to 2008 for the hell of it. I didn't have .net framework 3.0 installed(only 2.0) but I updated to 3.0 for the hell of it. I deleted all of my codecs. I reinstalled my driver. No luck. I crashed in the Dead Space menu. I wonder if it's a DRM/secuROM issue. I've never had a problem with that B.S. before. I'm thinking about a SP2 reload and just not installing fallout 3(why would I heh). You have any luck?
