Vista - Microsoft Corporation Name Grayed Out at Start UP

Before I start my new problem, I would like to ask DELL-Bill B to read by
previous problem
"Re: XPS 710 Does not always wake up from sleep "
I answered him thanking him for solving my problems.
Now for a different problem:

This morning when I turned on my computer, the screen that shows Microsoft
Corporation came up with the Microsoft Corporation name very light that you
could hardly see it. The green/yellow lights that usually crawl across as it
is booting up do not appear and the screen just sits there doing nothing.
I then turned the machine off.
When I turned it back on, I get the screen that asks, do you want safe mode,
last good configuration, normal boot, etc.
I selected last good configuration and that worked.
Why did this happen?
Any ideas?
I had turned it off at least once during yesterday and it did not happen.
Just this morning when I turned it back on.
