Thx for the reply.
I am running one monitor.
AV is Norton 360, I do have Malware Bytes Free installed and some other free and trial programs (that I only run manually, once a month). Its seems like this flash has been occurring before the installs as well.
Can you direct me, how to check if a program is loading (or doing something) to cause the 2 second black screen flash...? I have looked in msconfig "startup" nothing looks out of the ordinary to me (but I may have overlooked something). I will admit that I have not gone thru disable/restart for each and every startup item or service to investigate further, but I have read a lot about this problem.
I am wondering if this is something I am just going to have to live with...?
I have read the post you included however I don't show TMM in the Mobile PC folder (btw I have a Dell Desktop with OS W7 Ult 64)... the only thing showing in Mobile PC folder is "Hot Start".
