Hello, apparently this was the reason of my problem , but yesterday after playing half hour SH4 , after updating some drivers , I was trying again to play a little bit more the SH4 , but was not possible anymore , the PC was running normal but in the screen of the PC was given me some errors etc excuses when trying to play SH4(from the beginning this new PC was given strange noises from the optical DVD player ,the optical DVD player in my older PC is a dead silent Sony) finally I took out the SH4 DVD from the drive , and the DVD was severe scratched in the middle (before was brand new without any scratches) ,today I went to the shop where I bought the DVD player to change they told me to come back the next week to take a new one ,is only available another maker " Samsung "thank you very much for all your help and advice , thank you a lot
