New video graphics accelerator, do I involve to update driver?

I could not play Sims 2 at adjectives, so I upgraded to 1 GB of RAM and had a unsullied graphics accelerator installed. The game plays but crashes adjectives the time. I get a VPU restore your health message or one that says it have crashed and the application will now cancel. If I need to update a driver, how do I do that myself and where on earth do I go? I enjoy tried closing background tasks and disabling virus protection, but zilch is working. Any help will be greatly appreciated!

Answer:
VPU rest is a feature exclusive to ATI cards. nVidia might hold something similar, I don't know, but if so it's called something different. Anyway, dance to ati.amd.com and go the the 'drivers and support' subsection and download and install the latest drivers. If you don't know what video card you hold installed, right click on the desktop, go to properties, settings, advanced, adapter.

If updating the drivers doesn't work, contact whoever installed the card and bring up to date them your problem.

It might be that your power supply isn't powerful enough to run the card. Modern graphics cards are tremendously power hungry and it's not unheard of for one to have to upgrade their power supply to upgrade their video card.
what is your video card and possibly i can help
