Hi, My system takes a lots of time to start up. Specifically between the first screen where Windows logo shows up and the last where my username shows up, in between that, there's a blank grey screen where it holds for way longer then usual. As I understand it, on the first screen, OS loads up system drivers and on the second screen, the userprofile. What is that grey screen for, that appears right in between the two ? My old system with far less resources boots 3x faster then the newer one. It makes me sad Hard disks are fine, no fragmentation. Rest of the system, once booted, works like a charm. I'm using a customized copy of Windows 8.1 with lot's of stuff removed and updates integrated. I'm sure there's quite a bit I can do to improve it. I use to use Iobit's Advanced system care that had some tweaks build in for fast response time. Then my system use to start significantly faster. I forget in which sequence I use to use those settings. They don't appear to be working now. Any help will be greeatly appreciated. Thanks for reading.
