Yesterday I turned off desktop effects and power control, left my computer on 
for the rest of the day and all night and the problem did not show it's ugly 
face. I just enabled power control this morning and I will wait a couple hours 
and see if the problem returns if not, then I will disable power control and 
enable desktop effects and see if the problem returns.

I'm pretty sure it has something to do with one or the other.

I remember a while back when the desktop effects were first introduced in KDE 
and before I got this new monitor, I had to disable desktop effects, because 
after I would do a fresh install, desktop effects were enabled by default and I 
could not get a desktop, just a black screen.

I fixed it at the time by disabling desktop effects and low and behold kde would 
run with no problems.

How I figured this out was after a fresh install I got the black screen. I 
didn't know what was wrong, so I did another fresh install, and this install 
didn't enable desktop effects by default and I was able to get a desktop. Well 
I didn't know desktop effects were not enabled and as I was setting up my kde, 
I noticed this so I enabled the effects and viola my screen went blank.
