Hello My first post in the forum (unfortunately with a problem) So, recently I bought a new PC. After 10 days of usage, I discovered, that there is a very strange small desynchronization between audio and video. This is a contant effect. I notice it while watching movies and playing games. The lag is between 0.5 and 1 sec So, I posted here and there but noone could give a decent advice. Little details on my configuration: MB - Asus P8P67LE RAM - 8GB DDR3 1333 Video - GF9800GT (the vc is from my previous configuration, so I have used it for 8-9 months and haven't noticed the problem till now) CPU - Intel i5 2500K 3.3GHz Monitor - NEC AccuSync LCD73v (I know it's old. Do you think it can be the reason?) OS - Windows 7 Ultimate Basically, my thoughts are that it is unlikely the problem to be in the Video Card or Monitor, because they are from my previous configuration and I have never had this problem before Can you give any advice what can be the reason for that?
