Poor graphic card would explain the problem with Operation 7 and maybe Combat Arms, but I can't see how a graphic card would affect updating process since patches and stuff are usually downloaded via the launcher, not the game itself.
And because software problems are usually easier and cheaper to fix than hardware issues, I prefer starting to fix uncertain problems from software side.
E: @olik: no matter how new and expensive your computer is it still might be a hardware issue.
E2: @olik: But I still think this is a software issue.
