[BNW] Visuals and user interface broken/corrupted graphics?

So, here are two pictures of my civ 5 bnw. This happened after I tried to install some mods through steam, I usually download them manually since its more reliable and when I started, I had about 70 mods prior to adding these few new ones, this glitch or bug, dont know how to name it happened. First it only affected matches with mods, so I went mod by mod, to determine the fault one, but didnt find one...
Then it started affecting my single player regular games, I tried reinstalling, checking for file integrity through steam etc..
Nothing seemed to help.
I cant play with any mods, if I do, even my SP gets wrecked again :S
Currently I can only play without mods, and every other time or so, I get the glitchy screen again and have to restart my laptop. But the problem is there.
Is there something that can be done to help me, or do I go to pirate bay and fix the problem that way?
p.s. It affects some games on MP too, sometimes...
usually it happens on start up, or if Im unlucky on resyncs.
p.p.s. These images were nothing, usually I get a sea of corrupted graphics and its realy frustrating. The game from the images is usual SP, no mods, it was playable, but not enjoyable at all!!!
