I have a Gateway 700X computer, that is about six anhd a half years 
old, running Windows XP Pro, LG Monitor, ATI 9800 Radeon Pro graphics 
card and a Hauppauge video card. Except for the monitor and video card 
everything else is original. Over the last two weeks or so, during 
startup, vertical lines resembling bar codes appear on the Windows 
startup screen, the Gateway startup screen and the desktop as well as 
around the mouse pointer. In conjunction with the bar codes 14 of 26 
icon pictures (the wording is still there) do not show on the desktop 
and the screen resolution comes up small. The picture produced by the 
video card is mostly tiny green squares. The first thing I did was 
update the graphics card drivers by going into add or remove programs 
and using the ATI uninstall utility. After reboot, Windows searched the 
web for the latest drivers and installed them. The desktop and mouse 
pointer came up with no bar codes and all but 5 of the icons 
reappeared. The screen resolution changed from nornal to large and the 
video card functioned normally. When I shut down and restart the 
barcodes reappear, icons disappear, and screen resolution goes back to 
small. Every thing repeats if I uninstall and reinstall the drivers 
again. Can anyone give me some direction as to what is going on.
Thanks in advance for any help.
