I did something similar at least.  I have two drives in here that are 
for my OS.  I have a third that is for data, videos, audio stuff and 
documents.  The data drive is a 750Gb.  The old main OS drive is a 160Gb 
and the spare OS drive is a 250Gb.  I downloaded a stage3 tarball.  I 
then set up the spare OS drive and mounted the partitions basically 
following the docs.  I then copied over /etc, disfiles and the world 
file.  After that, I did a emerge -e world which installed everything 
that I had before.  It also has a slightly newer kernel as well.

So, after running my memtest this morning while I took a nap, I booted 
into the new install.  I checked with the mount command to make sure I 
was in the new install too.  I deleted EVERYTHING KDE in my home 
directory.  After that, I logged into KDE.  A box popped up that 
composite was disabled.  It said I could hit shift alt F12 to enable.  
After I started Firefox, it locked up complete with my keyboard lights 
blinking again.

What does Fluxbox use as opposed to KDE?  Both use the Nvidia drivers 
right?  I use KDM for my login screen and I think nvidia is loaded when 
it starts and it uses nvidia thereafter.  So, if it was the driver, 
would it not mess up in Fluxbox too?   What makes Fluxbox work and KDE fail?

Could my video card be having issues?  I may take the sides off and 
unplug replug everything and give it all a once over.  Maybe just a bad 
connection or something.  Maybe?

If one of you guys were me, would you order a video card and try that?  
Keep in mind, I have surge protection inside the UPS on the wall side.  
I also have a surge protector strip that my modem, router, puter and 
monitor plugs into.  It's kind of hard to imagine that a surge could 
make it through all that and not at least smell up  the place a bit.  
I'm not saying it couldn't but just hard to imagine.  I got surge 
protection coming out the ears here.

Thoughts?
