GTA 4 can't get computers to work

I can't get computers to work, except one that is in a warehouse near the 2nd apt you get.all computers was working earlier until i installed a few mods (new posters for the houses), and some cars. When i get near a computer it does NOT display "E" to access, except the computer i mentioned above.
Exactly where is the control for the computers and to get that symbol to show up?

And don't bs me on a illegal game. Too bad I have a legit game.
 
Interesting. This seems to be some type of corruption of the game. Created a new game, and all computers work fine again. Aka I get an "E" when near a computer. It would have been nice if someone had an idea of what created this bug. I"m saving more separate saves just in case it's some type of bug created by a mission. Again, anyone have ideas about this bug or at least what file?
