Ok so @ nut :

-I got my computer this christmas, so it don't need anything to clean or whatever lol...
-I use the last version.
-You're talking about what kind of driver?
-Like i said, it's a new comptuter, so there is no dust at all...

@ XMSFel6 :

Why not? as i know Windows 7 is just the OS, but all computer are different... so maybe DeSemu have freezing issue with Processor like AMD Atlon...

@ Manivo : I already try this way ... but it also freeze...

And btw, the game work, there is no problem with the speed or whatever... Just that sometime it freeze my computer, and then i need to critical shutdown my comp =x

If you have other solutions, i take them ^^'
