I just started really getting into this game. I orginally bought a foreign edition to Fallout New Vegas. It would play fine; never crash, but would freeze for a few minutes after several hours of play. I liked playing so much that I was ready for Honest Hearts and Dirty Money...one problem though...my edition didn't install through my Steam account. So, I go out a find a brand nib North American version...I uninstalled the foreign copy that required 3 disks to fully install. Next I make sure all FNV files are deleted, restart my computer then load the new game to install...it came with 2 discs, but only used disk 1 to install... this time it installs in Steam. Now I can't play 5 minutes without my pc crashing. Until I can figure it out I've uninstalled the software again.

Any help would be greatly appreciated.
