Random crashes, gfx gliches

[Halps]

So I bought G&K, forgetting that this prob is why I quit Civ5 in the first place, and now I really like the new game but every 5-15 mins I get random crash in which the game just locks up.
I have updated my GFX driver and here is my dxdiag:

It is usually preceeded by some graphical errors such as: Leader screen being nonexistent/buggy, terrain going blank, icons changing, etc.
I remember when it first started happening, it coincided with some patch and never got fixed.
I have used steam to "verify integrity of game cache" several times. Each time, it says "1 file failed to verify and will be redownloaded". When I start the game up again, downloads a "patch" then starts up.

I have un -> re-installed both Civ5 and Steam itself to no avail.
I also cannot choose DX9 OR DX11, it just goes into whatever Steam feels it should.

Any help would be much appreciated! I love the new G&K and would really hate to have wasted my $$ on a game I can't even play

Did I give enough information? Does anyone see anything wrong with my hardware?
I tried to go through the forum and find the answer without posting a thread but nothing has worked...

Well, the graphics card is directly at the min. specs...if your graphics settings are not set to low, then this is what you should try.

Turned everything down graphics-wise and no change. I only have 32 bit windows so it only recognizes 3.25 gigs of ram and the map is "huge" so I ordered 64 bit windows and I'm waiting for that to come in.
I don't see how that could be the problem though, as it used to work just fine with the same settings.

Update for future users who have this problem:

Crash was getting worse and worse the longer the game went. I usually play huge map so I thought maybe I didn't have enough RAM. Why it started being a problem after some random patch long ago, I don't know...
Anyway, I got more ram hoping that would fix it. Turns out I had 32-bit windows which only recognizes 3GB of ram. Upgraded to 64 bit windows (which recognizes 16GB) and put all 6GB of my ram into the computer and voila!

It now runs silky smooth into the industrial era(as far as I've gotten so far, standard speed) on huge map, turns go much quicker, and no crashing at all.



TLDR: Random crashing = not enough RAM. 3GB is not enough for Huge Map and you may need to upgrade your windows if you want more than 3GB.
