I have a problem with welcome screen.when I enter my log-in pass it delays for about 20-30 sec and during this period Hard disk led doesn't show any activity. I tried every thing like defrag, stopping windows desktop management service ,and stopping all services. but none of them worked.I have win7 sp1 and using raid 0 config. I don't have such a problem when I boot up in safe mode(with/without networking) . I'm running win on standalone computer not network.Any help really appreciated.I couldn't generate summary.xml because it says I should do sth about min and max buffers and it lost some traces How to solve this problem
