- Were there ANY software changes between day 1 and day 2? Any BSOD's you may have missed if ya left it on overnight? Check your logs under administrative tools.

"No, when it happen, it lagg on all games, even on the laptop, but it stops in a day or month"
- So this issue happens then stops? Need to be more specific here, your first post makes it sound like its a permanent lag issue after a certain day, but this message here indicates it happens then stops. What happens when you reboot and try playing the game again? When's your antivirus or malware programs scheduled to scan? What programs are you running period? If you run hijackthis and post the log we'll have a better idea.
