Not sure if this will help but....
When I first start my computer "Bios Splash Screen" stays on for about 20 seconds. Then it loads windows.
When I press tab this is the text I see.

AFTER 20 seconds....the following text loads very fast and the windows splash screen comes up. (had to record this part with a camera and go frame by frame to catch it)
