Nope. No other third party/security programs installed.
Window 7 Ultimate 64bit.
I've read from other forums that Avast is most likely the cause of it, Im sure it is cause what i've said earlier is that ive uninstalled avast, installed another antivirus, and bam, grand chase runs, and i can play smoothly without any interruption.
I dont think grand chase is causing the BSoD. I dont want to change our anti virus program so i hope you guys could help me with this.
