OK this is getting so annoying know.... When i try a game incompatible with vista, it doesnt work, i tried setting it to windows service pack 2, i found out it was already switched on but it its still incompatible like always. Could this maybe be a problem caused by having vista pre-installed on your new computer?

I had Vista pre-installed, I've yet to have a problem that could not be fixed by changing compatibility mode.

What game are you having trouble with?

[EDIT]
Yay 200 posts!

The most annoying issue is Silkroad, after 30 MINUTES of trying to log in due to crowded servers, the game freezes in the character selection screen. I know its supposed to crash the first time i log in BUT i cant seem to exit the nonresponsive game, then when when i alt+tab out to pick another program to do, THEY ALL JUST TURN BACK ON THE FROZEN SILKROAD SCREEN. I tried restarting my comp, the screen resolution expanded by at least 3x, i was forced to go on the highest res to get back to normal size.

Kinda Offtopic: I try to install Silkroad on my XP comp, it just said please wait..., then it says temp folder error then it exits...., i think its to big of a file since they combined europe and the original client together, my comp cant handle to big of a file or else bad things happen.

For some things, it just doesn't work. Virtual PC might be worth a try, but other than that, you might just not be able to use it.

Whoa.....know my problem has changed (idk if i can login without it freezing) but it shuts down the comp while im trying to log on

Hmmmm....

Reinstall, if that doesn't work then system restore (non-destructive kind that only restores settings)?
