Define "absolutely adorable nerdy guys." If you've set your standards too high on, "I want someone that likes all the things I do and is *hot* too," then we'll you've set yourself up for the same lonely frustration most nerdy guys set themselves up for. :-D
If you just find nerdy guys hot in general, then join an online dating service, look for LAN parties, college anime clubs, spend times on forums dedicated to games & other geek related things, go to SF/fantasy conventions, comic book shops, technical colleges and science / math majors at more broad colleges, etc., etc.
In other words, go to where the nerdy guys hang out and be nerds. It's not like there's a shortage of us compared to nerdy guy loving gals.
As the old phrase at Georgia Tech went, "The odds are good, but the goods are odd."
Put yourself in places where cute nerdy guys are, comic book conventions, Blizz con, being nerdy and putting yourself out there to find a relationship in the nerd community isn't as hard as you might think (or as difficult as it may have been before comic conventions and such), especially for the lady nerds, the ratio's a lot better for them... you.
I think any girl can attract a nerdy guy. If all they do is play video games, they probably don't meet many girls. I was never a video game guy, but was very shy up until 21 or so, and I would have dated any girl who talked to me because I never could approach them.
