Fallout games Hate me, Help?

So, i have been playing Fallout NV for about 2 hours, i modded it prior to actually start playing it. just visual mods, (texture packs, ENB, and Nevada skies.) after about 2 hours of gameplay, it  crashed after i died, and got sent back to my quicksave. I restarted the game, it did not crash upon startup, but whenever i tried to load any saved file, it would freeze and say FNV is not responding, and i had to use CL+ALT+DEL to get out of it.

while i was playing i had fallout 3 GOTY downloading, and when it finished, I installed it. but when i click "Play" on the launcher, it just stops responding, and not a single windows opens up besides the one that says it's not responding.

PC specs incase it's relevant: 

GPU XFX R7950 3Gb @955 mhz core clock, used to be at 1050 but it's gotten warm where i lived.

Drivers (GPU) catalyst 14.2

CPU: I7 3770k @4.2 GHZ

16 gb kingston hyperx ram

OS: Win 7 Home premium 64 bit

 

so yeah, I looked around online, but most of the post were from people who modded fallout 3 and got the crash, i had a fresh install, never before installed. and steam isntalled it along with all the DX stuff. and it just didn't work form the start.

run boss if that doesn't find the problem get rid of all the mods and star over adding them in one by one 

 

that's the thing, fallout NV crashed while playing, it ran fine with the mods, but Fallout 3 was a fresh install. ihad never had it on my pc before that, and it just, it was dead on arrival. just not responding

Did you install Games for Windows Client? LINK FO3 would not work at all until I installed Games for Windows and did a few other things. Here is the guide on how I got my Fallout 3 GOTYE to work LINK

I had the same problem with FO3 and GTA4. If you don't have the games for Windows LIVE client installed, most of those old games won't work correctly. Try what Theonewhoisdrunk posted. If you are still having issues after that, let us know.

I am still having issues, made an account downloaded it, everything, fallout new vegas Seems to run just fine, until i click on it with my cursor (fake fullscreen) and in normal launcher and the FNV 4GB launchers aswell

if i leave it like so. then it just stays on, i can see the animations of the character just standing there, dust, Etc.

 

fallout 3 just doesn't launch.

I got fallout 3 to work just fine, but fallout new vegas is still crashing, after i disabled all the mods
