Resolution Problems

I turned on my I8000 today to see that my resolution is, i think, smaller than 640x480! But I'm pretty sure it's my active desktop, but here's the real clincher...I can't even see the whole window of my preferences to change the resolution back. I'm running WinME on the dumb thing still. Is this a version of safe mode or what? Anybody know the correct number of tab keys to hit to get to the resolution changer on the settings? Again, WinME, Geforce2 Go.

And I've read quite a bit on this forum about the ability to change the video cards in these things. Which cards can I change it out with to get better quality?

Thanks for any help.
