@Cloud12: Can you post an updated copy of your dxdiag?
@ryanjrqwe: The system you have is out of date in several ways. Primarily it is because the CPU is quite a few years out of date. We have moved on to newer, better, faster, more powerful technology since the Intel® Core™ 2 Duo processors. Additionally, 4GB of RAM is a good amount for most things, but for gaming you are going to see significant performance improvements from something with 8GB+. However, your system is also running a 32-bit OS, you would want to upgrade to a 64-bit OS to take advantage of additional memory.
@Oakman: Thanks for the information 
We'll look into this option the next time a similar situation arises.
@RcnS: Try this driver; Download Center
Thanks everyone,
