Intel(R) G33/G31 Express Chipset Family
 

Hi, I have a HP Pavilion A6632F with 4GB RAM, 2.4GHz Duo Core Processor, and a Intel(R) G33/G31 Express Chipset Family graphics card. I can't get Call of Duty2 or Battlefield2 to run on my computer. When I try to run BF2 on my computer, the banner comes up, the screen goes black, then it closes. I don't think it will run on my card, but I've found different things on the internet.

When I run CoD2, I get an error message saying "DirectX has recovered an unrecoverable error." Do I need a new card and PSU (I currently have a 250W PSU, pretty bad, I know), or do I just need to install the latest patches for these games?

You need a new video card and a more powerful power supply if you want to play games on your computer.

Even games from 06? Because I don't care about the games they're releasing now. I mean, I can play Battlefield vietnam, MoH:AA, CoD, UT2004, etc. I don't need something that's top of the line. Or anywhere near the line, for that matter.

Both Battlefield 2 and Call of Duty 2 are power hungry pieces of code. I could barely play Battlefield 2 on a 256MB 6600GT on my old computer. I don't know the exact specifications of that integrated video card, but I can't imagine it being enough to run these games. However, try updating to the latest drivers and see if that will help you.

That video card/chip is bottlenecking your entire system.

Hmm...well, that wasn't the answer I was hoping for, but I appreciate all the time. Any idea how much a typical computer store would charge to install a 450W PSU? I plan on calling some stores, but I'd like to have some idea first so I don't get gouged.

450W power supply can cost anywhere from $20 to $100+ depending on the brand. I suggest going with proven brands to ensure more than a month of functionality. Thermaltake, OCZ and Rosewill (in order from most to least expensive) make good power supplies.

Actually.... I've played COD2 on a laptop with a 965G graphics card. It worked quite well at low detail, so your G33/G31 graphics card should be able to run them as well.
However, if you want to play more games, I agree you should invest in a proper videocard and power supply. Just make sure you can actually fit them in. In the past, I've seen big-brand computers (Dell) without AGP slots, and wouldn't be surprised if your computer can't fit a modern PCI express videocard.
