On my new PC (GA 790XTA UD4) after POST the Windows screen appears, with the
blue things swiping across the screen about 20 times. Then all is well. On
my old PC there were only about 5 'swipes' of the blue dots before loading
completed. I'm wondering what's going on during that time that takes so
much longer on my new super speed (?) PC.
TIA
What mode is the disk interface in ? AHCI perhaps ?
Some disks don't support NCQ (Native Command Queueing),
which is a part of AHCI. Presumably they should be telling
the driver that fact, so NCQ can be disabled. NCQ allows
completing disk commands out of order, so that the disk controller
on the hard drive can reorder them. But a downside, is sometimes
the boot time is longer when using AHCI.
In Safe Mode, there is an option to turn on "Boot Logging", but
it sadly lacks timestamps for when the drivers are loading.
I found this, Bootvis, which gives a graphical trace of startup
activity. But in reading the description, apparently it can
"hose" a system (it wasn't stated exactly how it managed to
achieve that - you'd think just tracing system activity wouldn't
be that dangerous, especially if the instrumentation capability
was already built into the system).

As long as you've got a backup of C: , what could go wrong ?
