PC Freezes When I Exit

[BMWebb]

I just started playing CABAL yesterday. I really enjoy it, but when I exit the game, my pc freezes. I've let it sit for a few minutes to see if it was just taking a while, but no response. When I say freeze, I mean the entire pc. The mouse won't move. Ctrl+Alt+Delete does nothing. It's a laptop, and it won't even go to sleep when I close it. The only way I get around it is to turn it off by using the power button.

I searched Google and this forum and couldn't find a solution.

My laptop's specs are:

Windows Vista Service Pack 2
3GB RAM
2.00 Ghz AMD Turion(tm) 64 X2 Mobile Technology TL-60
89.4 GB free space
NVIDIA GeForce 7150M / nForce 630M


The game runs smoothly, and has acceptable loading times. I don't lag really at all. But when I exit, my enitre PC freezes. Anyone have a fix?

I'm really sorry for double posting, but I really want to know if anyone has any idea I should try. Should I completely uninstall, then reinstall it?
