Dude, you waited for only like 20 minutes. Give it some more time, it may take around 5 minutes for the thread to even shows up - add in extra time until somebody actually clicks it and another 5 minutes or so to write the reply.
With that said, I haven't played any visual novels but Here are some other games you might enjoy:
Vampire: the Masquerade - Bloodlines Vampires - check. RPG - check. Can you run it - check. Go and play one amazing game. Came out in 2004, so you should be fine. Oldschool...well, I wouldn't call it one, but I've seen the term applied to it here on the Escapist - apparently because it's 8 years old it makes it one. But anyway, it's well worth to have a look at it. Do note that you need the Unofficial Patch [http://www.patches-scrolls.de/vampire_bloodlines.php] to iron out a lot of bugs. The only really annoying thing is that it's expensive - $20 on Steam. I may praise the game, but that's a lot of money for it. If you wish, you can wait until Halloween - it's going to be on sale then for sure.
Arcanum: of Steamworks and Magick Obscura is on GOG and is an RPG and is old. And it's awesome. Made by the same guys who made Bloodlines. Also, they are partly responsible for Fallout - I'd say if you liked the first two games, you might be interested in Arcanum. You need another Unofficial patch [http://www.shsforums.net/topic/33528-arcanum-unofficial-patch-extras/?s=939c72e7377917b07e022f028f7ead5be] for it, though, just giving you the heads-up.
And at this point, I can just say GOG. Just go to GOG and hit the RPGs - most are pretty good and they all would definitely run on your machine. Well, perhaps aside from the Witcher 2 maybe Witcher but everything else is fair game. If you're unsure, just check some of the GOGmixes [urhttp://www.gog.com/en/mix/gogs_rpgs_cream_of_the_crop_1]like[/url] these [http://www.gog.com/en/mix/must_play_classic_crpgs] ones [http://www.gog.com/en/mix/great_crpgs] or others.
Another game I can recommend is Cthulhu Saves the World - it's on Steam and you can buy it in a bundle with Breath of Death VII for $1.50. An unfairly low price, if you ask me, but whatever.
