Oblivion and Dell D620

Hey guys. I'm having some issues with my D620. I got Elder Scrolls IV: Oblivion for my PS3. It's a really good and fun game, but i wanna try out playing it with the mods some people have come up with. So i bought it for PC and installed it on my D620. The problem is that every time i click "Play" in the main menu, the quickly says "Oblivion has stopped working" and then it exits Oblivion. Can anyone help? I don't know much about computers. I'll get you whatever information you need to help me out. Just let me know what you need. Thank you.

 

Here is some system information

What are the PC system requirements?

Recommended:

* 3 Ghz Intel Pentium 4 or equivalent processor
* 1 GB System RAM
* ATI X800 series, NVIDIA GeForce 6800 series, or higher video card

The video card in your D620 is not even close.

 

Two major points:

Oblivion is known to not work well, if at all, with the GMA 900 and 950. Even if it did work, you cannot expect decent performance without tweaking it to have as bad as graphics as perhaps Morrowind.
Oblivion sometimes has issues with audio codecs installed on the same computer.

The only advice I can give you is to look up the mod called 'Oldblivion'.
