So here is my problem. I had a friend build this pc for me awhile back. It's a decent computer but when playing games like Fallout 3 I usually run at a solid 60 fps but occasionally drop in to the 40 fps area. Which isn't to big of a deal. At other times it can drop to 15 fps or lower. Which is definitley something that ruins the game play.

I'm not very computer savy which is why I had my friend build the computer. I just tell him I want something good enough to run X game and he runs off and builds it. Therefore Im not 100% sure whats in it. Yes I know I should pay more attention but that's a topic for another day.

Anyway here is a screen shot of some of whats running my computer

I figured I could try upgrading this myself but since I cant afford to do it all at one time and Im not sure where to start. Would it be better to start off with a new video card, more RAM, buy a new motherboard and processor? Any advise would be greatly appreciated.

If any other stats or more info that could be helpful please let me know, I just wasnt what sure would help or not.

The reason I don't see DD going mainstream anytime son is this.

Even now in the US only 63% of adults have high speed internet. That leaves a big group of people out of your sales.

I would imagine the percentage gets lower in other areas of the world.

I am at work at the moment but what I can remeber is it has a Nvidia Geoforce GTX 260, Intel Core quad q950 and I believe 4 gigs of ram(though I can't remember what type of ram) and is running with Windows 7.

Sorry this is so vague

I am not particularly computer savy, I know the basics but nothing fancy. Anyway I have just gotten a new gaming rig built and everything seemed to be running great until I tried playing Farcry 2 and Call od Duty: World at War. Both play fine for a couple of minutes and then lockup or crash to desktop. Well in trying to figure out what the problem was I noticed that one fan in the back of thetower (out of 3) doesn't seem to be running. My question is, is that one fan not running enough to shut down a graphic intensive game?

Of course I will replace the faneither way but I am just wondering if this could be the problem or if I need tokeep looking.

I thought this one was pretty epic
