I finally got it fixed.  It was definitely a graphics issue.  I changed the resolution from 1920 x1200 to 1920 x 1080.  I also changed the DPI from 154 to 145.  This may be the sole issue since the default setting for large is 120 DPI.  In Windows Media Player under tools, options, performance,I checked  turn on direct X Video acceleration for WMV files so this was not the issue.   In Windows Media Player when turning on enhancements, full screen, frequently I got a black background with white horizontal marks.  By checking fit video to player on resize and fit player to video on start, this problem was fixed.   I have the Samsung 245BW LCD.  When playing games for some reason they display as a square instead of filling up the whole screen.   
I have the Inspiron 530 with Windows Home Premium 64 bit.  The computer is only two months old.  I have never been able to get into Riox DE 10.2.  Every time I click on the desktop icon the mouse pointer freezes and so does the entire computer.  Pushing Control Alt Del does nothing; the only way to get the computer to work is to turn it off and then on again.  I have tried reinstalling it.  Same problem.  I have also tried adding the activation patch 133853.  If I install a CD in the computer I can get into Roxio, but it says it needs to connect to a network.  It looks like it is trying to install files, but never works.  I have Norton 360 installed.  I also changed the number of processors to start the computer to two instead of one.  This boots the computer considerably faster.  Should I try installing it again with the Norton firewall turned off?   After reinstalling it, under System Restore, instead of being listed as one entry titled "installed"  it lists about 10 entries all in small increments.  In order words the time sequence is, installed 11:25 p.m., installed 11:39 p.m., installed 11:40, 11:41, 11:42 etc.  At no time does the word Roxio appear.  The volume is not dirty.
