I've had a black screen and working cursor for around a minute after entering my password at login. The desktop eventually comes up and everything appears normal. Is there anything that could be running such as the Malicious Software Removal Tool or other program? Would the Event Viewer be any help in finding out what is running? Even with a normal boot the screen blinks black for a second or two before the desktop comes up. I believe that is normal. Running new Windows 7 (64 bit) computer with i5 processor. Memory is 8 GB.
