I love those types of posts. Here are a couple of generic suggestions.
First, tell us what video card you are using and what game you are
trying to play. I'm sorry, but your Integrated Intel Extreme Graphics
with 4 MB of Memory is not going to run Doom 3. If your card is fairly
new and it isn't playing games that it used to play well, try removing
the drivers/software you installed for it and install the latest version.
