|First thanks 4 replying. And Yes , i think i installed all the drivers correct , i mean sound is OK , Intel extreme graphics is also at its right place , and everything else as good as it can be . All those drivers from the resource cd(Motherboard CD) i got from the manufacturer with my machine.|
If that's really the problem , maybe i will uninstall all the drivers and reinstall them again , and will reply if it works . Thanks again.
