Hello, Thanks for your reply. DxDiag show no errors, and i have reinstall cleanly my card driver (whql) and no more amelioration. But, i have safely restore my computer and TPE works ! I don't understant what happened after running AdwCleaner, it's probably a fake positive in their rules ? But i have checked the log, no trace about TPE... But, it's work now, i would like to thank you ! Sincerely,
