i get the blue crashes but i have 1 gb of RAM O_O
That's it, i got the same shit before untill i bought a new computer.
I had 4 GB of RAM and a 284MB vid card *something like that* *my old computer*.
It crashes cause your video card cant handle when alots of thing start to happen on screen.
I often got this when lets say, 2 artillery call ins were called along with a enormous firefight.
Do your screen flicker when its about to happen, it did so for me.
Solution: Use tactical map for 8-10 secs, the flicker gives up then.
2GB ram is adviced for CoH but meh i think its your vid card.
And yea, i got bluescreen also before after lets say 3 matches it freezes to 1-2 secs then it says: nv4_disp.dll dumping files e.t.c.
It's your graph card as you have explained now.
