is there any way at all to check it without opening up the side of my computer, like a program?

No, there are no programs that will tell you what power supply unit you've got. You just need to remove the side panel. There's a label on the side of the PSU that will show the model number and total watts.

The Geforce thing you downloaded was probably a graphics driver update.

Download the latest driver for your 9800GT from here: http://www.nvidia.com/object/win7-winvista-32bit-257.21-whql-driver.html (GeForce 257.21 for Vista-32, June-2010)

Open Device Manager, click the [+] next to Display Adapters to expand it, right-click your graphics card entry and click Properties. Click the Driver tab and click the Uninstall button.

When it's finished uninstalling, close down all programs, reboot the computer and install the driver you downloaded earlier. Reboot again to complete.
