Hello guys, I'm having problems with the Windows 7 that I installed few days back. I just wanted to test-drive the new 7, mine is Build 7100. I installed Windows Server 2003 and Windows 7. Server 2003 only detected 1 HDD instead of 2. Now, when I'm playing HD movies in Win 7, it lags. Sometimes, normal DVDrips lag too. Don't know what the problem is. Server 2003 is playing movies but lags when playing 1080i/p videos. Everything played well when I had Windows XP and Vista Ultimate. The CPU usage is normal (14-16% during HD movies) and memory is OK too. What might be the problem ? Have you people ever faced such problems ? My friend claims that his one is running smoothly, he has 3yrs old PC. My config is given below in the signature. What might have gone wrong ? I will install Vista soon but what's the problem in Server 2003 ? I've all the required codecs (K-Lite Codec Pack).
